Sizing Your Solar Battery Bank

Worried about power outages or just looking to back up critical loads? We can size your battery system to ensure you have adequate reserves to meet your energy goals.

Thankfully, our systems provide backup power that is adjustable depending on the size of the inverter, the size of the battery, and more. There is no limit on our battery sizes.

Inverter Options

Our systems pair any inverter option with one of the premium battery technologies below. For inverters, we’re proud to offer the rugged Outback Power Systems Radian line of inverters, which we’ve been working with in our projects for nearly 20 years. With excellent reliability and a virtuous customer interface, the Radian series offers both grid-interactive and stand-alone capabilities in the same package.

House Backup (16 kWh)

This power level is recommended for whole-house power or for critical loads that are very large or likely to be operating at the same time such as a clothes washer and well pump.

Examples of appropriate loads include all the appliance listed under the 4kW inverter plus mini-split HVAC units, central air conditioners, and most individual power tools or compressor-based tools.

Large Home (32 kWh)

This power level is recommended for whole-house power or for critical loads that are very large or likely to be operating at the same time such as a clothes washer and well pump.

Examples of appropriate loads include all the appliance listed under the 4kW inverter plus mini-split HVAC units, central air conditioners, and most individual power tools or compressor-based tools.

Expandable (up to 144 kWh)

A battery storage system that is expandable is designed to allow for additional batteries to be added to increase the total storage capacity.

Your system can start with a smaller storage capacity and grow over time by adding more batteries to power additional loads.

This type of system offers flexibility and the ability to adapt to changing energy needs over time.

Benefits of Backup Solar Batteries

Independent Power partners with premium battery manufacturers like SunPower, Humless, and Rolls Surrette to offer best-in-class energy storage solutions for grid-tied and off-grid applications. Each battery is safe, reliable, and comes in a variety of sizes and capacities to meet your project’s energy needs.

Power when you need it most
Solar panels work during the day, but at night or on cloudy days, the solar batteries provide reserve power.

Lower electricity bills
In areas with time-of-use rates or demand charges, batteries can help save energy during periods of high demand.

Reduced carbon footprint
Solar + storage helps you use more environmentally friendly energy, which means less pollution from fossil fuels.
