Battery Charging in Utility Mode (Line)
The battery charging path is shown in the following figure.
The Alpha Micro 100 comes standard with 2 sets of 9AH batteries. The maximum charge current is limited to 3A.
The charge current can be set to 0, 1, 2, or 3A.
The Alpha Micro 100 can deliver full power to the AC load and charge the batteries at full capacity, simultaneously.
8.2.5 Back Up (Inverter) Mode
When the Alpha Micro 100 detects loss of utility, it opens the Grid Relay (preventing AC power back feed) and pro-
vides AC power from to the load (in 3 to 5 msec) by inverting DC voltage from the batteries.
