2. Power on the battery stack by first switching the breaker to the ON (closed) position, then briefly
pressing the Power button to the ON position. If in parallel, turn on the Power Button first, then switch
the breakers to the ON position.
If using the SLIMLINE enclosure, follow the manufacturer instructions for turning on the battery stack.
3. Program the inverter with this battery's appropriate charge/discharge settings.
4. Enable “BMS Lithium Batt” and set its value to “00.”
