The leftmost GEM 120 meter in my Gateway, which I think is the one measuring the PV, seems to be working but it is flashing red. Can some kind person tell me what the fault is and how much to worry?
My system is an AIO with Gateway. The inverters for the 2 separate PV arrays feeding into the Gateway are a SolarEdge and a Solis.
Complete guess here but AIO only has 1 PV input as far as I am aware so presumably your feeds are combined before the gateway. I think the theoretical limit is 10Kw input, are you getting over that?
Hopeful Thanks for the suggestion. The two arrays are on opposite sides of the house i.e. east-west and each has a capacity of 4kW max. In reality, particularly at this time of year, it is unlikely the combined would be above about 5kW. I think the theoretical AIO max is 6kW i.e. this is the max it can be charged at.
SteveT Hi Steve, it can charge at 6 but can handle 10Kw PV input as it sends the rest to house/grid before considering winding back the PV if it hits the export limiter. My setup is limiting the PV to 10Kw but I know people who has hit 11 without blowing the 40a breaker in the AIO. At 5kw my guess was off base for sure though.
