3. Installing the SBU
Install the SBU between the grid and the inverter. Connect cables to the grid and loads. For details, refer to the SBU user manual.
4. Installing the battery
Install the battery. For details, refer to the battery user manual.
Warning: On one battery, do NOT connect its positive port (BAT+) to its negative port (BAT-). This will short-circuit this battery, causing serious
battery damage.
Note: For regulation compliance, you can install a battery isolator ≥70A near the inverter, except that you are using the Eletopia B2 battery
model which has a built-in DC isolator in its high-voltage box unit: B2-7.3-HV5, B2-14.6-HV5, or B2-21.9-HV5.
5. Opening the wiring compartment of the inverter
1. Use the Allen Wrench to press down four locks on both sides of the inverter. Then, remove the cover.
