How many battery strings can I install with the XW/XW+/CSW Hybrid Inverter/Chargers?

In general no more than 3 battery strings for the battery bank (Trojan allows up to 4 on their web page - the less the better charge balance:

For LiOn type batteries, in some cases you will need to use more than 3 strings for the application but they have their own Battery Management System (BMS) that will ensure batteries are kept in good health and you can install string protection for single or dual strings.

For Lead-acid types (flooded, Gel and AGM) cell balancing across multiple strings is an issue that even using a common busbar will not protect from the problem as the string nearest to the power source will get more charge and those close to the loads the more discharge currents than the others.
