system 24 volt. One battery bank 200AH. Two chargers in network. Ip22 16 amp and mppt 100-20. When I put this in synchronise charge the mppt stops charging and ip22 takes the lead. I have managed to work them together by removing the network and adjust charge voltage on the IP22. So the ip22 charger only kicks in at a lower voltage. Maybe this issue will be sorted in a new update so that when solar power is available the main charger will not kick in if it is not necessary.
