How do I turn off my battery correctly?

Answer: 

How you shut down your battery depends on the type of battery you have.

BEFORE shutdown (the following steps should be carried out for both PSM and Pylontech ESS before shutting down the battery):

1. Charge the battery to 40-60% in battery level/SoC.
2. Put EnergyHub in Measurement mode: This is done either by pressing "Stop" on the EnergyHub display or via EnergyCloud under "System Configuration" --> click on the red Stop button under "Operation mode" and make sure the system enters Measurement mode.
3. Wait for 1 minute before shutting down the battery according to the instructions under Shutdown of PSM and Pylontech ESS below. NOTE: It is not necessary to break the AC connection to EnergyHub to ensure that the battery does not charge/discharge.

AFTER shutdown (the following steps should be carried out for both PSM and Pylontech ESS after shutting down the battery):

1. Put EnergyHub in Operating mode: This is done either via the EnergyHub display or via EnergyCloud under "System Configuration" --> click on the button under "Operation mode" and make sure the system enters Operating mode.
2. PSM and Pylontech ESS can be shut down for a maximum of 90 days. This is to avoid the risk of the battery being damaged due to self-discharge and reaching too low cell voltage.

Shutdown of PSM and Pylontech ESS

NOTE: Consult your installer if you need guidance. 

PSM

Turn off the AC supply to the battery's controller (BMS). How to do this depends on the on-site installation. It can, for example, be done by unplugging the connector (if it is plugged into a 230 V socket) or by switching off the circuit breaker in the electrical cabinet that supplies power to the battery.

NOTE: Simply turning the knob to "OFF" on the PSM controller is not sufficient to put the system in standby mode. See image below.

ESS

Turn off the switch at the back of the battery's controller/BMS (referred to as the "Power Switch" in the manual). See images below.
