My brother runs a few years a Solar Home Power Systems and is now switched from 12V to 24V a facility. The device is of 3 in series 55 watt modules powered by a solar controller spannungdfesten and 2 in series lying 12V 200Ah batteries a turn. Until now, he had a regular 0.6 kW Garden Pump off the runs and runs, etc., and even a garden pump with 1.2 kW, this was about 2 hours nonstop before the inverter has switched off and the battery had to be recharged. The instrument is very robust and the housing provided with cooling fins and at high load switch on the device Cooling fans on until now is still no fault or defect to notice and my purchase was based on already existing good reviews, so far at least a recommendable device.
