3. Installation
3.1 General
● Mount vertically on a non-flammable surface, with the power
terminals facing downwards.
● Mount close to the battery, but never directly above the battery
(in order to prevent damage due to gassing of the battery).
● Use cables with at least 10mm² or AWG6 cross section. The
recommended maximum length of the cable is 5m, in order to
restrict cable loss.
(if the cables to the PV panels must be longer than 5m,
increase cross section or use parallel cables and install a
junction box next to the controller and connect with a short
10mm² or AWG6 cable to the controller).
● Grounding: the heatsink of the controller should be connected
to the grounding point.
3.2 PV configuration
● The 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 open circuit PV voltage: 100V.
The controller can be used with any PV configuration that
satisfies the three above mentioned conditions.
For example:
12V battery and mono- or polycristalline panels
● Minimum number of cells in series: 36 (12V panel).
● Recommended number of cells for highest controller efficiency:
72 (2x 12V panel in series or 1x 24V panel).
● Maximum: 144 cells (4x 12V or 2x 24V panel in series).
