Charlesk Posted September 7, 2020 Posted September 7, 2020 Has anybody had an issue with kodak king inverter not picking up the pv array. Watchpower said that pv loss. Thanks Quote

Thanks What panels are you using and how is it connected? Fuses? DC breakers? Did it work before or is the a new install? Quote

Hi, No the pv icon is not on and the pv voltage is 0. The pannels have been on my previous inverter and was working fine. 4 sets of 3 pannels 320w pannels Each set is 120 v Quote

Fused and with dc breaker, yes they worked before in just swaped the inverter out this weekend my previous one was just an inverter charger. Quote

Sorry, i did not set it out clearly. 4 strings of 3 pannels each, so 120 v at +- 36bamp Quote

I groan every time I read this. 120 V is quite high, and it will get even higher in colder months. Kings may be more sensitive than other models with respect to high PV voltage. I can't think of a good reason why; the SCC should be identical to those of an Axpert MKS model. It might be worth isolating to just one string, and rewire to 2S for that single string, to see if it suddenly recognises the panels. Or perhaps see if the PV is recognised early in the morning or late at night, when the panel voltage is under 115 V (the maximum MPPT voltage). I assume you're seeing the 120 V on a multimeter right at the PV input terminals. francois 1 Quote

Watchpower said that pv loss. Thanks I have this exact problem. It happens as soon as the batteries are fully charged, usually around midday. Quote
