Synapse 4,0+ Inverter Fault

Good Day All,

Some advice please,I have a CB Solar synapse 4.0+ with a flashing LCD brought to me for repair.

I replaced the 5 smoothing caps,some were bulging, in attached picture.

The inverter powers up now with no errors on LCD but charger LED stays off with no charging voltage going out the battery leads,not sure if this can be disabled in setup ?

It worked in tandem with a second inverter and shows H5 on LCD.

Something else I noticed is the large heatsink on the left hand side in the attached picture is running quite warm even while only passing the mains supply through the inverter.

All other heatsinks all stay cool.

Inverter does start up on mains fail.

Is this normal or does it sound like  there are further  faults ?

TIA
