Benefits of batteries for solar

  • 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.

Sizing your battery bank

Worried about prolonged power outages or just looking to back up critical loads? In any case, you’ll need to size your battery system to ensure you have adequate reserves to meet your energy goals. Thankfully, the degree to which our systems provide backup power is adjustable depending on the size of the inverter, the size of the battery, and whether you choose to incorporate a generator or not. There is no limit on the size of the battery we can offer.

How Solar + Storage Works

A battery-based system provides a ‘reservoir’ of electricity that is ‘refilled’ by your solar panels when the sun is shining. At night or during an outage, you can then pull this stored energy from the batteries to power your critical loads! Premium battery storage solutions like the sonnen ecoLinx even pair with your other smart home automations to further optimize your energy management.

We offer scalable solutions to ensure your battery system is sized appropriately to meet your energy needs. From off-grid cabins to advanced microgrids and resiliency projects, we have decades of experience working with all kinds of battery technologies.

Inverter Options

Our systems pair any inverter option with one of the premium battery technologies below from sonnen, Sun Xtender®, and Blue Planet Energy. 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 twenty years. With excellent reliability and a virtuous customer interface, the Radian series offers both grid-interactive and stand-alone capabilities in the same package.

Larger inverters should be matched with a larger battery. Additional inverters can always be added if you are considered a future expansion of your system for increased power. Custom inverter systems can be built up to 80 kW.

Safe, reliable, resilient
