FAQs

Overview

Who is HomeGrid For?

There are two primary ways that customers of any size can benefit from owning a battery:

First, you can use the battery for backup power. If the grid goes down, you’re still covered. If disaster strikes, having a battery will allow you to continue to have electricity in your home or business, even if your utility company can’t provide it. You can choose to back up vital circuits (lights, wifi, etc), or back up your entire home. Several entirely off-grid projects are already supported by Homegrid systems.

The second reason is that you can actually save money by getting a battery. Even though solar can produce a lot of net power, it stops when the sun goes down. A battery allows you to store the excess power from solar during the day and use it to power your home or business at night.

HomeGrid is perfect for customers who:

Are grid-connected but experience power outages or need to maintain power for vital circuits.Many customers have systems in place that they need to keep online. Homegrid is a primary power supply that completely insulates the home from any utility outages. We can support all loads in a home or business, regardless of whether the grid is up or not. For residences, HomeGrid can deliver up to 14.4 kW of continuous power and 16.8 kW of peak power per unit, effectively replacing a 200 Amp utility service. For businesses, we have options all the way up to 100kW of continuous power with MWh capacities.

Have no utility power or choose to live off the grid. Homegrid systems are perfect for off-grid living. We can connect an inverter and solar/wind/water power to keep electricity running no matter what.

Want to eliminate demand charges and arbitrage time-of-use utility power rates? On its own, our battery systems can help offset high demand charges for homes and businesses. They can also be used for time-of-use price arbitrage, and when paired with solar/wind we can drastically reduce or eliminate electricity bill on a massive scale.

Want solar but cannot or do not wish to net-meter. HomeGrid does not require grid-tie which allows you to have solar even if your utility does not permit grid-tied solar. HomeGrid also enables you to have solar if you simply do not want to net-meter.

Need more power, but utility line upgrades are expensive. Some customers have an existing utility connection, but experience higher peak loads than the utility connection can deliver. Those customers can use a HomeGrid battery to provide the needed power and avoiding costly utility line upgrades.

Experience poor power quality and need to protect sensitive electronic equipment. Some customers experience unstable grid power with low line voltage or power spikes, which can damage sensitive electronics. The Homegrid systems provide a quality-controlled, consistent power supply.

How can I control HomeGrid?

Each battery has a display that shows vital data for the battery. Our residential batteries are inverter-agnostic, meaning that we are compatible with most inverter systems on the market. This gives our homeowners and installers a high degree of flexibility in the equipment they use. Control of the battery output is delegated to the inverter of choice, many of which have fantastic user interfaces and apps. Our larger products on the commercial scale have their own user interfaces built in.

What is HomeGrid?

Homegrid is a battery manufacturer based out of Henderson, Nevada. Our product applications range from powering tiny homes and cabins to utility-scale power storage and everywhere in between. A Homegrid setup can use and store energy from solar, wind, the grid, a generator, or any other power source.

Can HomeGrid work without internet?

All Homegrid products will work perfectly without the use of internet. Most inverters on the market will have user interfaces that are improved with an internet connection, but this is not typically needed.

Solar Integration

Does HomeGrid work with any solar panel?

Yes, however, compatibility has more to do with the chosen inverters or panel-level rapid-shutdowns/optimizers/micro-inverters. If you have any questions regarding system compatibility, feel free to contact us at any time.

Is there a solar package with HomeGrid?

Yes, we frequently work with quality contractors to install solar with our Homegrid batteries, and recommend doing both solar and battery backup at the same time due to increased efficiency.

How large of a solar array can I connect with HomeGrid

You can connect an array of any size, however, you will find that the limiting factor tends to be the inverter of choice. Charging rates will be limited based on the product you install. Please see our resources page to view each products’ specifications.

During a power outage, can my solar recharge HomeGrid?

Yes! This is one of the great benefits of adding a battery to solar. Most solar will NOT produce electricity when there is a grid outage. This is to keep electricity from going back to the grid during repairs or to keep emergency personnel safe. When paired with Homegrid, solar energy that is not used goes on to charge the Homegrid battery. When more solar energy is available than can be used or stored, many inverters can route the excess and sell it back to the grid.

Can I add HomeGrid to my existing solar system?

HomeGrid can be integrated with existing solar arrays. Depending on the existing system, the needed configuration will change. We have numerous systems installed that are either AC-coupled or DC-coupled to existing solar.

Do I need to have a rapid shutdown of the solar array for firefighter safety?

This varies greatly on region and the location of solar on your property. We recommend consulting with a local solar installer. If you contact us, we would be happy to put you in contact with an installer in your area.

Generation Integration

Does HomeGrid work any exisiting backup generator?

Yes. Homegrid can work with any generator depending on the inverter pairing. Generators with remote start can be automatically turned on and off by many inverters.

Can my generator charge the HomeGrid battery?

Yes. Depending on the inverter chosen you can integrate numerous power inputs.

Can I use a backup generator with HomeGrid?

Yes! When paired with an all-in-one inverter such as Sol-Ark, you can easily input generator power into your home and battery. This is the most effective way to use a generator! As an example, if you have a 10kW generator but you are only consuming 4kW of that, normally the excess goes to waste. If you use your generator to charge a Homegrid battery, there is no waste because it is stored in your battery to be used later.

Wind, Hydro, or Fuel Cell Integration

Can I charge my electric vehicle (EV) with HomeGrid?

Yes. All you need to do is configure Homegrid to have enough power to support your electric vehicle charger. Your system may also require a larger battery if you want to charge at night.

Can I charge my EV on HomeGrid during a power outage?

Yes. During a power outage the amount of energy stored is limited to solar production and what you have in the battery. If your setup includes a generator, then it can add energy to the Homegrid battery for EV charging if solar production isn’t enough.

Can I charge my EV at night from solar stored in the batteries?

Yes. You just have to match the right amount of battery storage with your charging requirements. If you know that you typically charge your car with 10kWh at night, our 19.2kWh could be a good option to make sure you have leftover capacity for other uses.

I have a wind turbine/hydro turbine/fuel cell. Can I integrate it into HomeGrid?

Yes. You can integrate most DC and AC inputs into a home-backup system. The chosen inverter will provide the right integration depending on the power of the energy source and whether it delivers alternating or direct current. Some wind turbine/hydro turbine/fuel cell may have controllers that make integration difficult.

Can I add a fast/super-charger to a HomeGrid?

For larger commercial projects, our Gridbox options can support fast/super-charging. Unfortunately for typical residential projects, even a 200 Amp utility service is not enough power for fast/super-charging. Residential products, such as our Compact or Stack’d Series can support Level 1 or Level 2 EV charging output.

Off-grid Use

Can HomeGrid Products start without any external power?

Yes. Homegrid batteries hold their charge for a very long time. We ship the battery with an existing state of charge. The moment a battery is connected to your system and turned on, the system begins to operate.

Can I use HomeGrid products off the grid?

Yes. Our batteries are perfect for off-grid use. Our LFP (lithium iron phosphate) formula means that our lifespan is much longer compared to other battery types. Our batteries are made to stand up to daily cycles for 25 years, making them the best choice for off-grid reliability.

It also means that we are safer! Other formulas can explode or leak acid if they are damaged or punctured, but LFP won’t. You wouldn’t want the device that powers your home to burn it down!

Functionality

How does HomeGrid work when the grid goes down?

This can vary significantly depending on other equipment and how you and your installer decide to design your setup. In most cases, customers choose to have a critical load panel with an automatic transfer switch. This simply means that you select certain circuits that will be kept on when the grid goes down. Most residential customers choose to keep everything online except for high use items such as their AC/electric dryer/etc. but, as long as you size your capacity correctly, Homegrid batteries can easily back up your entire home/business. Some inverters on the market, such as Sol-Ark, can automatically switch to critical loads in 4ms.

How can I monitor my system?

You can monitor basic statistics and battery usage on the display. Each of our battery systems has one and you can view battery capacity, health, and other basic information. The inverter of choice will also have a user interface that allows you to view the statistics and functionality of your battery, home, and solar.

Does HomeGrid net-meter?

Yes, but this has to do with the inverter equipment you or your installer has chosen. An inverter such as Sol-Ark can be set to automatically sell back excess solar if the battery is charged and the home isn’t using enough solar power.

Can the HomeGrid battery charge from the grid?

If you are on a time-of-use plan, then you pay more for electricity at certain times of the day. This is typically in the evenings, right when electricity usage can be at its highest. Even if you do not have solar, a battery can save you money by charging at night when electricity is the cheapest, and discharging that power for your use when electricity is the most expensive. If paired with solar/wind, this benefit is even more apparent.

Backup Power

During a power outage, how quickly can HomeGrid restore power to my home?

This will depend on your inverter setup. Sol-Ark inverters have a response time of 4ms, meaning you won’t even notice that the grid has gone down. Other equipment manufacturers also have very fast response times. We are inverter-agnostic to allow you and your installer to choose the best equipment for your application.

How many appliances can I back up with HomeGrid products?

This is entirely up to you! Homegrid batteries can provide enough power for massive commercial buildings, so this has more to do with your budget constraints. We can effectively replace your utility service if this is a concept you desire.

Most of our residential clients choose to supplement their whole-home power with the battery each day, and if the grid goes down, they choose to back up everything except for their high-usage items such as AC and electric dryer. This is typically the most cost-effective option. Usually our Stack’d Series 19.2kWh or 24kWh can supply enough power for this.

During a utility power outage, how do I extend the amount of time my home can run on battery backup?

The best way to extend your usage of Homegrid products during an outage is to limit the energy consumption of your home. You can do this by turning off high-power appliances like air conditioners, electric dryers, or electric stoves. The less electricity you use during an outage, the longer your battery will last! If you have a small generator that feeds into the battery system, you may not have to reduce consumption at all.

During a power outage, how long will HomeGrid batteries last?

This depends on your usage and what you decide to back up. A typical small single-family home uses 35 kWh, a mid-size home 50 kWh, and a large home 70 kWh or more per day. These consumption estimates exclude EV charging. Luckily, you don’t need that big of a battery if you have solar. For most homes paired with solar, our 19.2kWh or 24kWh Stack’d battery will keep the lights, internet, fridge, and small devices on indefinitely during a power outage. Please see our sizing recommendation tool or call us with questions related to system sizing.

What happens if I overload the system?

It is possible to overload the combined power of the grid connection, battery, and solar that feeds the inverter. To avoid this, we recommend that you size the system to cover the peak power in the house comfortably. (We can help you figure out your estimated peak power). However, if you ever were to overload the system, some inverters have built in breakers that will trip in order to keep everything safe.

Installations

Can I add more solar, batter storage, or a generator later to a setup containing HomeGrid?

Yes. For residential applications this is one of the best selling points. Our Stack’d Series is Lego-like and can easily be expanded by adding additional modules.

What does a HomeGrid system look like with all the additonal equipment installed?

This depends on the product! Our Compact Series is wall-mounted, our Stack’d Series is ground-mounted, and other products are entirely weatherproof to be mounted outdoors in commercial locations.

For most residential installs, the system will consist of our Lego-like Stack’d Series in the garage, and a wall-mounted inverter next to it that your solar/home are connected to. See our product pages for more information or pictures.

What are the different componets that make up a home battery system?

Typically an entire home battery system is comprised of a battery, solar, and inverter system. An all-in-one hybrid inverter such as Sol-Ark keeps everything in your setup simple and efficient.

Does a home battery require a permit from the utility?

In most cases, your local jurisdiction will typically require a permit for installing a solar array and any power equipment. This varies greatly on region and you should consult a local installer or electrical code specialist to confirm what is required.
