I bought two Multiplus II 48/5000/70. On both inverters, the connection terminals to Battery missing(or not?) connection plate. Please check attached photo.
Unusual design of the battery connection terminals or a incomplete series.
Never before seen that type of connection. Is it ok or defective series?
Hello community. I have this exact issue, the Bat - terminal block does not have the strong metal plate the Bat + terminal has.
It can't be correct to torque 12 Nm onto essentially PCB board coated in a thin film of metal...
Have you considered reading the manual?
Thank You for fast reply!
My problem is that Positive and Minus connection plate are different. Positive has special steel plate, but on Minus is only an PCB (there is place for steel plate, or maybye I'm wrong). Never before on any connection point saw that solution
@janusz_sebek I have the same. No issues when connection the cables. I didn't feel any concern when tightening up the connections.
Hey Jason, thanks for adding. I'll be listening carefully for "crunching" when tightening!
The conduction pathway then must be from the upper metal surface through what looks like 48 x, 1 mm diameter holes, giving only a total of 37.7 mm^2 conduction pathway.
Kinda makes a mockery of adding 70 mm sq cables to it. This is surely a Hotspot when the current is flowing?
@John Gordon I have changed to 70mm2 cables on my now. They fit with no issue.
