7.1 Sizing the array
We recommend to use the MPPT Sizing Calculator available on our
•
The solar charge controller will operate only if the PV voltage exceeds battery voltage (Vbat).
•
PV voltage must exceed Vbat + 5V for the controller to start. Thereafter minimum PV voltage is Vbat + 1V.
•
Maximum PV Array open circuit voltage is 250V.
•
Maximum PV Array short circuit current is 35A.
For example:
•
Minimum number of cells in series: 144 (4x 12V panel or 2x 24V panel in series).
•
Maximum: 360 cells (10x 12V or 5x 24 panel in series).
Remark: at low temperature, the open circuit voltage of a 360 cell array may exceed 250V, depending on local conditions
and cell specifications. In that case, the number of cells in series must be reduced.
The MPPT component of the EasySolar-II GX is pre-programed to 48V to match the requirements of the included
inverter/charger.
7.2 Connection
1. Connect the battery.
2. Connect the solar array to the M6 solar bolts. Note: if connected with reverse polarity, the controller will heat up
but will not charge the battery.
Note that the 100 Amp fuse is not end-user replaceable. When blown, the unit must be returned to a service agent for
repair. It only blows after other components in the device have failed
