My Victron multiplus 2 is not turning on

Hi I installed a Victron Multiplus 2 inverter 48v/5000
But after installed I have no sign of any indicator after battery is connected. Also it is not turning on
Connection are good but my wire is thin as the guage.

At the battery bank it is showing 48v but in each
Some batteries are showing 12v and some are showing 7.6
Help me guys

Can you draw or explain how everything is connected?

I guess your battery is under the minimum required by the multiplus, please check or post the inverter settings.

Can you please post another picture with only the MP2 connections?
Thanks!

I did the program in mp2 by the Victron connect and it is working fine

What batterys do you have and specs, if its actually wired like you draw it, its not good…

All wiring looks way too thin!

Yes battery wire is bit thin as the guage it’s problem

I think you have multiple problems why your system wont start

Battery bank size?
Batterys should be charged full individually and then connected, also inthe right way

Wiring is way too small

I suggest you start with reading the multiplus manual and the wiring unlimited manual

You can also always ask your local official victron dealer for advice

Sir unbalance battery bank
cost the inverter not turn on?

It needs a big current to start, if voltages of batterys are low, voltage will drop even more of high current and with to thin cables voltage will drop again

Thats why it probably wont start
