Thanks so much

Hi All. Simple question for thee panel of experts. Please see image attached. The inverter has 3 mppt inputs. 2 pair are circled in black, 1 pair circled in black. My question is regarding the MPPT input voltage of 650Vdc. Is the the total amount of voltage combined for all the MPPT inputs or is it per input.? And are they recommending 550Vdc? Thanks in advance.

That is the problem, the supplier is being told by Herholdts its not their battery. If i take the 2 batteries back im left with nothing for whatever period of time they squabble about it. What use is a 10 year warranty if they dont support the battery locally.

Afternoon All. Could anyone assist with where to get firmware upgrade for the Sunsynk Model SUN-BATT-5.32. Ive tried to get the firmware upgrade from Sunsynk and they say I must get it from Herholdts. Herholdts say it must come from the original supplier whom i contacted. When they ask Herholdts for the firmware upgrade, Herholdts says its not their battery according to serial number, which has the supplier stumped. When i contact Sunsynk they say its not their batteries!? Then their standard reply is "Reach out to Herholdts". Im tired of reaching out. Anyone experience this same taking no responsibility for the Sunsynk batteries?

Hi All. Does anyone know where i can have a HOSELECT battery repaired?

Thanks so much Jacques.

Good Day All. Im new to the site. Thanks for all the helpful information posted. My question relates to cable colour from the PV panels to the MPPT input. Is it legal to use black for both + and -, then use red heat shrink to identify the + cable on termination ends? Thanks in advance.
