[QUOTE="hcbeynonhc, post: 542258, member: 36383"] I have a givenergy pv installation consisting of: GEN1 1 3.6 kw hybrid inverter and 2 strings of 4 ja Solar JAM54S30-405mp modules. Data sheet for inverter states: starting voltage = 140V and a max input current = 11A Data sheet for module states: STC Voc = 37.23V, Vmp = 31.12V and Imp = 12.98V. NOCT: Voc = 35.12V, Vmp = 29.47V and Imp = 10.38A Both strings are on the same roof. With no shading. The inverter does not start to generate until the monitored pv votages by the givenergy app reach 150V. This has not always been the case. Previous data shows the pv voltages at which the generator started were in the low 140’s. My installer suggests having one string of 8 panels Into one mppt input. My questions are: Why doesn’t my inverter start to generate at or above 140V. Is the inverter faulty? WI’ll I have more power one string or two strings? Are there any other implications on 1 string Vs 2 strings. Thanks for any advice you can offer me. [/QUOTE]
