9.2.3 MPPT Solar charger + MC4 PV
connectors
The MPPT (Maximum Power Point Tracking) Solar
charger is necessary to connect to the ESS a PV power
module.
It is necessary for any solar power systems and allow
to extract maximum power from PV modules; it
forces PV module to operate at voltage close to
maximum power point to draw maximum available
power. They are 3 pairs of MC4 connectors included
to connect to the PV module. Each pair limited to
30 Amps.
PV module / solar panels are not included in the scope
of supply.

1a) If more PV power is connected, the con-
troller will limit input power.
1b) The PV voltage must exceed Vbat + 5 V
for the controller to start. Thereafter the
minimum PV voltage is Vbat + 1 V.
2) A PV array with a higher short circuit
current may damage the controller.
