June 28, 20233 yr Hi Guys, Could you please give some advise. Have a Kodak OG10 and looking to add PV to the system. The specs state that OG10 - 10000Watts (2 x 5000Watts per MPPT) and Open Circuit Voltage of 450Vdc. With this inverter having 2 x PV inputs just a bit confused with regards to the Open Circuit Voltage. Is the 450Vdc the total voltage or 450Vdc per MPPT? The panels specs as follows: 500Watts / VOC 45.59vdc Having 2 strings of 9 x Panels each in series, so 9 panels in series to PV input 1 and 9 panels in series to PV input 2. Each string will have to following value = VOC-410.31vdc & Pmax-4500Watts Input 1 = Voc 410.31vdc & 4500Watts Input 2 = Voc 410.31vdc & 4500Watts Will this work?

June 28, 20233 yr The MPPT max is 450Vdc on each MPPT with a max of 5000W per MPPT. Your Panel consideration is good.

June 28, 20233 yr I'm sure you know this. Mppt normally has a voltage range. A minimum-optimum-maximum voltage. 450 probably max. Seems like your panel selection have enough head room
June 29, 20233 yr I have a similar setup with the Kodak OG7.2. Two MPPT with 7x 545W panels for each MPPT. Just make sure you have four fuses and 2x 600V 30A DC circuit breakers installed between panels and inverter. Also remember your overload protection.
