Best Solar Batteries: Pick the Right One for Your System

Solar batteries are a wise energy storage investment. You won’t be able to store energy generated by your system for later use without a battery bank. If you’re connected to the grid, you won’t have any backup power if the utility system goes down. If you live off the grid, your system will simply not operate.

Batteries are critical to the operation of your equipment.

Many aspects go into selecting the appropriate battery for your solar panels, including the battery’s capacity, power, efficiency, and cost, all of which are dependent on your needs. Let’s take a look at how solar batteries operate, the many types of batteries available, and our suggestions for the best solar batteries in 2022 to help you make the best decision.

For Vacation Homes, the Best Off-Grid Battery

What if you have an off-grid vacation house you don’t use on a regular basis? Because you’ll only be on-site a few times a year, you’ll want a battery that doesn’t require regular maintenance.

A sealed AGM battery is the best solution in these situations. The 415Ah FullRiver DC400-6 is our top pick:

Because you don’t need year-round storage, the reduced capacity is beneficial. We also passed on the premium lithium option because it’s excessive for a system that will be utilized only a few times per year.

These batteries are reasonably priced. You don’t have to invest a lot of money in a place where you won’t be spending much time.

The Best Grid-Tied Backup Battery

You won’t need a battery with a lot of storage power if you have a grid-tied system with battery backup for emergencies. As a result, we propose the same battery as before: the FullRiver DC400-6 with a sealed AGM: FullRiver DC400-6 with a sealed AGM: FullRiver DC400-6 with a sealed AGM: FullRiver DC

You only use the battery when it’s really necessary. This battery will only be used if your electricity goes out, which should only happen once a year at most.

The grid-connected battery has a low maintenance requirement. You want a battery that doesn’t need to be maintained—it should just operate when you need it.

The Best Energy-Storing and Energy-Sale Battery


The power company in some places charges extra during peak usage hours (about 4 to 9 p.m.), when people return home from school and work.

You’ll want to be able to store energy produced throughout the day and sell it back when rates are at their highest in the evening.

The Discover AES 7.4kWh or the SimpliPhi 3.5 kWh are the finest batteries for your solar needs for this type of use:

You can use the energy storage to store energy during the day. You can make a profit by selling it back to the utility company.

Both lithium batteries with a voltage of 48 volts have a substantially longer life expectancy. Because the battery will be cycled more frequently than in a vacation home or battery backup application, we recommend lithium. In terms of cost-per-cycle over the life of the battery, lithium batteries can be equally as cost-effective as lead-acid batteries.

If you reside in an area with time-of-use rates (TOU), high demand charges, or no net metering, these batteries will safeguard you from future rate increases.

The Best RV Batteries, Marine Batteries, Remote Industrial Batteries, and Small Off-Grid Batteries

What if you need to power a smaller application on your property, such as an RV, boat, or small outbuilding?

Choose from the following options if you’re looking for a small battery with a small capacity:

Crown 6CRV220: The 6CRV220 sealed AGM battery is a solid solution for light-use applications. This battery, which was originally developed to power golf carts, has a very low profile yet can still survive deep cycling over a long period of time. This battery is ideal for tiny homes, boats, and RVs—anywhere where space is limited and you only need to power the essentials.

Crown 12CRV110: For remote industrial applications, we recommend Crown 12CRV110. It can power small-scale industrial equipment in regions where power lines aren’t available. Lighting, pumps, traffic signals, and monitoring equipment are examples of common applications.

The 6CRV220 and 12CRV110 are identical in terms of size and capacity.

  • 1320 watt-hours = 6 volts x 220 amp-hours
  • 1320 watt-hours = 12 volts x 110 amp-hours
