MultiPlus. input voltage 66V DC

Hi. I have a 48/3000 multiplus. In the technical book it is written that the maximum input voltage = 66V DC. But when it reaches 64.7V it stops. How can I adjust it to work up to 66V. Thank you

Hi. I use 26 batteries x 2V .

-I want to charge them from solar panels with the absorption voltage 2.53V * 26 = 65.8V. But when it reaches 64.7V it stops.


-I changed the battery absorbtion voltage from the inverter, but it doesn't let me setup an absorption voltage higher than 64 V. (I changed the type of batteries to let me setup 64V, but not more).


-I want to know how to make the inverter do not stop before 66V.(maybe 65.9V)


Thank you

Charging-I can't setup to charge more than 64V

Inverting-I can't setup to stop at 66V(65.9V)

Hi @ciprian dobrescu

ok, so to make sure: the Multiplus shuts down when solar charger charges to 64,7 volts?

how / where do you measure this? and what error message does the Multi give?


charging is only to 64 volt, that's normal.

in the manual is written the input voltage 66VDC
