Hi Ron, your batteries have different charging parameters, so your system would charge the batteries with the less amount of demand. In terms of longevity it’s best to have the same voltage and aged batteries in the same battery bank.
Hi Paul, you could connect it directly with an extension cord, but it would be better to use an automatic transfer switch. This would allow it to be powered up by the inverter automatically and prevent AC back feed when you switched over to shore power or generator power. There might actually be one in the system, but I would have this done by a dealer.
Hi Gordon, ideally the dealer that provided you these parts, but if not we can try to help as well. I would give our solar calculator a go first so you have an idea of the loads etc. I couldn’t get into it on the show but the IC inverter charger also has some other benefits as well.
