Battery Capacity
The default setting is for a battery with a 200Ah capacity.
Change this setting if your battery has a different capacity.
You can test battery capacity by following the procedure on
.
The most accurate way to find the capacity is to ask for the
manufacturer’s 20 hour rating.
Estimated Capacities for 12 Volt Flooded Batteries
The values listed below are estimates for 12 V flooded
batteries except when noted.
Estimated Capacities for Gel Cell Batteries
Gel cell batteries usually hold 15% fewer Ah for a given size.
For example, a Group 27 gel cell stores about 85Ah.
Estimated Capacities for Multiple Batteries
Parallel Connection
If you are using a single battery bank
that consists of two or more batteries connected in parallel,
multiply the Ah capacity of a single battery by the number of
batteries used. For example, if three 12 volt Group 27
batteries are connected in parallel, use 300 Ah (100 Ah x 3)
for the battery capacity.
