Connecting An Inverter - Victron energy MPPT 75/15 Anleitung

3.3. Configuration of the controller (see figure 1 and 2 at the end of the manual))
A four pin header is available to select one of three battery management options:
3.3.1. No jumper: BatteryLife algorithm (see 1.2.2.)
3.3.2. Jumper between pin 3 and pin 4: conventional (see 1.2.1.)
Low voltage load disconnect: 11,1V or 22,2V
Automatic load reconnect: 13,1V or 26,2V
3.3.3. Jumper between pin 2 and pin 3: conventional (see 1.2.1.)
Low voltage load disconnect: 11,8V or 23,6V
Automatic load reconnect: 14V or 28V
3.4 LED's
Green LED: will be on or blinking when the battery has been connected
On: one of the two conventional algorithms
Blinking: BatteryLife algorithm
Yellow LED: signals charge sequence
Off: no power from PV array (or PV array connected with reverse polarity)
Blinking fast: bulk charge (battery in partially charged state)
Blinking slow: absorption charge (battery charged to 80% or more)
On: float charge (battery fully charged)
3.5 Cable connection sequence (see figure 3)
First: connect the cables to the load, but ensure that all loads are switched off.
Second: connect the battery (this will allow the controller to recognize system voltage).
Third: connect the solar array (when connected with reverse polarity, the controller will heat
up but will not charge the the battery).
The system is now ready for use.

3.6 Connecting an inverter

The load output can be used to supply DC loads and simultaneously to control an inverter.
The Victron inverters model Phoenix 12/800, 24/800, 12/1200 and 24/1200 can be
controlled by connecting the right side connection of the inverter remote control directly to
the solar charger load output (see figure 4 at the end of this manual).
The bridge between left and right must be removed.
For the Victron inverters model Phoenix 12/180, 24/180, 12/350, 24/350, the Phoenix
Inverter C models and the MultiPlus C models an interface cable is needed: the Inverting
remote on-off cable, article number ASS030550100, see figure 5 at the end of this manual.
