2820 watt (2.8kW) off-grid AC bimodal solar systems is manufactured, pre-wired and pre-tested in the factory, ready to power-up on delivery to your site. A bimodal solar unit works in sync with the utility grid until the grid goes down. Once that happens the inverter on a bimodal system takes over and draws electricity off the batteries. When the batteries are full the solar panels are shut off automatically waiting for the solar equipment to signal when its time to wake up. The complete prepackaged solar, called “SunPods”, are delivered by truck and lowered into place with minimal on-site construction required.
