To
turn on
the BlackMax follow the steps below:
1. Open the lid (remove the two screws at the front left and right first), switch ON the battery breakers on the top of each
Troppo battery. The LED and display on each battery will come on. Check that the battery voltage on the displays is
reading between 48 and 55 volts. Close the lid.
2. Switch ON the BATTERY SYSTEM D.C. ISOLATOR (#4), found on the right side of the unit. The Victron battery monitor on
the top of the system will come on at this time as it is monitoring the overall DC battery status. It indicates the state-of-
charge (SOC) of the batteries. It provides the most accurate readings of SOC. Note that when the system is initially
installed it may take a few days for the SOC to calibrate, which occurs once the system has gone through a few charge-
discharge cycles. This also applies if an extra battery has been added to the system later (In this case also don't forget to
update the battery size in the Victron monitor so it can calculate SOC correctly, see instructions in the Adjusting the
Inverter Parameters in the section below)
3. Switch ON the SOLAR D.C. ISOLATORS (#3), found on the right side of the unit. and check the PV isolator on the left side of
the Inverter
4. Tu r n O N t h e A C c i r c u i t b r e a ke r s (#2), found on the left side of the unit. The GENERATOR USAGE METER (AC) will only come
on if there is power available from a generator or the grid.
5. Open the front door (using the supplied tool to open the two locks)
Press the “On/Off” button (#1) on the left hand side of the inverter.
The display in the centre of the inverter should soon reflect "ON" in
the middle. Please note, it may take 2-3 minutes for the inverter to
begin inverting. Once the inverter has started up fully the INVERTER
USAGE METER (AC) display on the left side of the unit will turn on
showing the AC voltage that the BlackMax is producing together with
the current and Watts going to the load. (either via the GPOs or a
hard-wired switchboard)
