4.4.6 Commissioning a single eFlex battery pack
Installation procedure for a single eFlex battery
1. Turn the eFlex on momentarily to check battery voltage.
Check that voltage between
terminals is between 50-55V. If the voltage is too low, a slow charging to 50V is needed.
Turn off the eFlex.
2. Put the inverter disconnect
into “OFF” position
(if there is any). Make sure the eFlex
battery and any charge controllers are off/disconnected as well.
3. Connect the eFlex DC positive and negative terminals
to the inverter.
4. Put the inverter
breaker into “ON” position.
Note: always turn the eFlex battery on
first prior to turning on the inverter. If a shut down is required, always turn the inverter
OFF first prior to turning OFF the eFlex battery.
5. Put
any DC charge controllers into the “ON” position.
6. Turn on eFlex unit
by pressing the
eFlex power button and waiting ~10sec until LED
diagnostic is complete. Under normal operation, the eFlex LEDs will show state of charge
after the diagnostic is complete. The red BMS light should not be on.
4.4.7 Commissioning multiple eFlex batteries in parallel
For a maximum battery bank size of 81KWH, up to 15 eFlex batteries can be connected in parallel.
All wires should be an appropriate gauge and constructed to handle the loads that will be placed upon
them. A qualified installer should understand this and must adhere to industry standards and
published electrical guidelines.
