don't buy at EASUN or POWLAND
I bought 2 EASUN inverters (5.5kw) and they came faulty. It has been 4 months I was making video's to prove that the inverters are not working. EASUN & POWLAND is the same company, DO NOT BUY FROM THEM! 3 out of 5 inverters they sell you are faulty. One friend burned his new Lithium battery because they sold him a faulty inverter that gave out 76 Volts at the battery output. I have many other stories from people. It is unbelievable. EASUN/POWLAND are box movers and not manufacturers. They have no technical experience. They will NEVER give your money back.
