April 13, 20224 yr Lately I have noticed a huge dip in PV generation during load shedding. I have checked a couple of things and what I noticed is that the MPPT is going nuts. Voltage would go down as current increase. Once it reaches 11Amps it looks tile the controller reset and goes back to Zero amps. This complete cycle takes around 15 to 20 seconds. Now this only happens if there is load shedding, meaning mains is off. According to the SEMS portal my load is jumping up and down, sometimes to over 7kw. We know this is not possible as the unit can only output 4.6kw during load shedding. Anybody else also seeing this problem? I have raised it with Goodwe in the past, but it took them 8 months to write a special software for my unit and the problem was still there. I would like to raise the issue again, but looking for Goodwe users that have the same problem. Thanks.
April 13, 20224 yr Perhaps a silly question, pure speculation, but what loads have you actually got connected? Anything that could intermittently cause a surge or spike in consumption without you realising it, like pump motors or fridges coming on, which might not be a problem in the presence of the grid? Geyser? It might be that you are exceeding the inverter's peak rating of 6900VA for 10 seconds before it cuts out and throttles back production to protect itself. 11 Amps sounds like the rated panel current at around peak production, which could support this theory.
