How about a system that can power multiple appliances such as a full size refrigerator\/freezer, 240V pump, microwave, lights and much more during a power outage? This kit has been designed for the user that needs to power several items, for short periods of time, easily and with little equipment. One battery, one inverter, one set of cables and a safety fuse kit. That’s it! But don’t worry….this kit is packed with power.\u003c\/p\u003e\n\u003cp\u003eThe 12000 watt pure sine inverter charger 120\/240V with a 36000 watt surge will keep your home, business or  large RV running as long as you have battery power. The inverter is packed with features including a powerful built in battery charger to recharge the battery when you have access to grid power. It also includes an automatic transfer switch that goes back and forth between grid and inverter power, automatically.  Also includes, auto generator start, battery temperature sensor, LCD\/LED optional remotes and dip switches to set AC priority. The two\u003cspan\u003e \u003c\/span\u003ebattery packs provide 400 amps at 48 volts! This battery replaces multiple batteries and cables.\u003c\/p\u003e\n\u003cp\u003eBuilt with lithium technology, this battery provides up to 8x more charge\/discharge cycles than a lead, gel or AGM battery.
