Y&H 10.2KW On/Off grid Solar Hybrid Inverter Built-in 180A Charge Controller PV Max 500V Input DC48V to AC230V Pure Sine Wave Inverter for Home Energy Storage RV Shed Off-Grid System

After few years I can say that the inverter is still alive, it's bad it noise! Noise from cooling fans, spins a lot and takes some energy from battery and solar panels.

purchased this inverter to go with a system that was being installed on my home address. various fault codes came up including internal fault in the unit, which did not correspond to the codes in a brochure enclosed. Had to wait for the qualified electrician to return to check installation....he stated that there is a fault in the unit. Supplied a video and pictures and attempts were made to fix it remotely and to turn n the unit in a particular sequence. it worked! i then went abroad for a month during which time it has stopped working. this unit has exported 9kwh of electric to the property in 4 months.....pathetic. The alarm now just sounds constantly no matter what sequence it is in. the fault code says internal fault return to workshop. the attempts for months at trying to resolve it remotely have failed. the return time of 28 days has of course expired. Y&H have now stopped replying to my what's app messages. all in all; my experience has been a product that has never worked from day one and an unsuitable method of response to a system that should be producing. once i started asking for a replacement.... the co operation or replies seem to have stopped once the problem means a return.steer clear of this product. it promises a lot; gives nothing in return
