Solar Panel Batteries

Solar Panel Batteries are links between the solar panels and the sources of electricity consumption that provide your house with constant electric power 24 hours a day.

Since the batteries stabilize the voltage that flows into the grid, they are used to store the excess solar energy and to protect appliances from electrical disturbances.

In solar systems, a deep-cycle battery is used. It's a rechargeable battery that provides a low stream of current over a long period of time (unlike a starting battery that gives off a short burst of high current). In off-grid and hybrid solar systems a battery can be used to run appliances at night while during the day you recharge it with solar power.

Batteries for solar panels are usually either lead-acid or lithium-ion:

  • Lead-acid batteries can be automotive (starting) or deep-cycle. The capacity of a lead-acid solar battery is measured in amp-hours (mAh). It’s easy to translate amp-hour into watt-hour — just multiply watt-hour by the voltage of your solar battery.
  • Lithium-ion batteries are deep-cycle by default. Their capacity is measured in kilowatt-hours (kWh). They are better than lead-acid batteries in almost every way, except the price.

Sizing your solar battery bank depends on what you plan to do with it. For example, if you need energy storage as a backup in case of power outage, first calculate your daily energy needs. You can do this by using electrical meters, looking at electricity bills or simply by multiplying the power ratings of household appliances by their hours in use one by one. If you want your solar battery to cover your energy needs for more than one day, multiply the daily needs by the desired number of days.

Take into consideration the depth of discharge (DOD) — batteries for solar should not be discharged below a certain level on a regular basis. Lead-acid batteries usually have a DOD of 50%, and lithium-ion batteries can be easily discharged by 80% and recharged back again. Constant deep discharge leads to an early death of a solar panel battery.

Choosing the right battery for solar panels

There are two main types of batteries on the market:

Devices that use grid photovoltaic and battery inverters. They redirect the excess electrical energy to the battery as well as have the ability to recharge it from the inverter output.

Devices that use battery inverters and DC charge controllers. They send the excess generated electrical energy directly to the grid.

Best brands of solar batteries

Enphase Solar Batteries

Enphase is famous for its microinverters but it also offers great options of energy storage. Enphase Energy batteries have a high charge/discharge rate, are 15% more space-efficient than traditional batteries, and are so light that the battery can be installed even on the wall.

Enphase also offers AC batteries. They use high-efficiency, non-toxic lithium-ferro-phosphate (LiFePo) technology. Enphase’s AC battery has a built-in microinverter which converts the DC from panels to AC, a battery management unit, a communications controller, and safety disconnects. The efficiency of an Enphase battery is commendable. It is capable of storing 96% of the solar power harvested by the PV modules.

Enphase battery allows you to use 100% of its capacity. This is what distinguishes a Li-ion battery from a simpler lead-acid rechargeable battery. The manufacturer warranties each battery with a 10-year replacement and guarantees it will last for at least 7300 cycles.

Generac solar system batteries

Generac has been on the market for over 60 years. The company was the first to develop low-cost standby solutions and continues to be the first in residential backup equipment. Generac manufactures batteries, inverters, power switches and other devices. They are engineered to work together as part of an integrated system that saves you money, reduces emissions and makes your home safer.

The integrated energy storage system is called PWRcell. Innovative design allows it to tap into and store both solar energy and the electricity from the grid. This way you will always have enough energy during peak demand hours, which means you have to pay less for your bills.

You can monitor the state of your PWRcell through your phone. PWRView app offers detailed reports on consumption, solar generation and Generac battery performance. All data is safely stored to be available when you need it. To further enhance your experience, the app has bill forecasting functionality and other insights.

Generac solar power battery has a 10 year warranty or 7.56MWh throughput. The battery cabinet’s warranty is also 10 years.

KiloVault solar panel system batteries

KiloVault is an American company that provides renewable energy solutions for residential and commercial applications. It designs, markets, and sells batteries and inverters. KiloVault keeps its product modern and helps reduce the impact of humanity on the environment.

The company has over 20 years of experience designing renewable energy systems. Their product is designed specifically to be paired with photovoltaic systems. KiloVault offers AGM and lithium-ion solar batteries for solar panels. The warranty for KiloVault products depends on a particular item and ranges from 1 year to 10 years.
