Battery Chemisty

Cloud Solar supports lead acid (AGM) batteries by default.

The Cloud Solar charge controller does support alternative battery chemistries but the settings must be changed either by a technician or can be done remotely by one of the Inclusive Energy team.

If you would like the settings to be changed, please give the battery chemistry, number of cells (or nominal voltage) and the battery capacity in Ah.

The following battery types are supported:

DescriptionTypical No. of cells for 12V application
Flooded lead-acid battery6
GEL battery6
AGM battery6
Lithium batteries (3.2V nominal)4
NMC/Graphite Li-ion batteries (3.7V nominal)3
NMC/Graphite High Voltage Li-ion batteries (3.7V nominal, 4.35 max)3

Changing the settings to different battery chemistries changes the battery charging set points. Here is a summary of those set points:

DescriptionTypical No. of cellsAbsorption / Full (V)Bulk (V)Float (V)Low Voltage Disconnect (V)Low Voltage Reconnect (V)
Flooded lead-acid battery614.413.214.111.112.3
