Hi I recently boaght a 2.5kva 24V inverter running x2 12V 200Ah gel acid batteries in series. I connected the balancer precisely like the instructions stated but my balancer still shows high voltage on lower battery even if I switch the batteries over it still shows the same light. The other problem is that the green on/standby light never switches on. Can someone please steer me in the right direction. Thank you
