Off-Grid Inverters

Off-grid inverters are essential for harnessing all that hard-earned renewable energy your system will produce. Providing the interface from your battery bank to standard AC plugs, many of our off-grid inverters also accept an AC source from generator or even the power grid, doubling as battery chargers to keep your deep cycle batteries charged and ready. As such, with the addition of a battery pack and DC load center, these inverters make for a highly effective “UPS” (uninterruptible power supply) to keep select circuits hot in the event of a power failure. This can be a far more cost effective technique than attempting to power your “whole house” from a battery bank. While these inverters can’t bank energy on the grid, they can be used as the UPS, and with the addition of a transfer switch and a grid-tie inverter with “secure power” feature (i.e. Sunny Boy TLUS-22 series), you’ll be the only one on your block not running a generator in case of extended power outages!


"You could convert all your household lights and appliances to DC, but joining the mainstream as far as appliances are concerned offers some definite advantages. AC appliances are mass-produced, making them less expensive, universally available, and generally of better quality."
