[QUOTE="stuboy, post: 545780, member: 33489"] I'm slightly unsure of your connection. Can you clarify, do you have one or two strings? If two equal strings then the voltages are dealt with totally separately internally so there is no doubling of voltage. Your inverter maybe running into thermal overload problems perhaps or you are getting current spikes from the optimisers maybe? Would be useful to put a current clamp on the inputs to check. I assume you are monitoring these values on the inverter itself and not the app? Cheers Stuart [/QUOTE]
