About Photovoltaic Energy StorageFloat charging in parallel should work well enough as long as you charge them to this state separately, as you say you intend to do. This probably violates the most proper method of long term maintenance where a "topping charge" is occasionally applied to floated batteries BUT this is usually only once per 6 months so probably an issue.
About Photovoltaic Energy StorageHere''s the deal. It is crucial to determine how to charge multiple batteries with one solar panel because the amount of energy dispensed depends on this particular number. The batteries connected to the solar panel are placed parallel. This way, the battery retains the same voltage but doubles its energy capacity. So, when you use …
