6.5 MAINTENANCE
6.5.1 Battery SOC Monitoring
The PM235J transformer unit features built-in state of charge (SOC) monitoring for the house battery. To ensure accurate display of this
information on the LCD monitor and in the app, the following conditions must be adhered to:
1. Battery capacity is set correctly in the LCD or app – refer to your battery specications.
2. When replacing a battery, ensure it is fully charged via AC mains for the rst time.
3. Fully charge battery via AC mains at least once every 3 months, until the ‘CHG’ LED light on the PM235J transformer unit remains on
(solid) or ‘oat’ shows on the monitor.
6.5.2 DAILY MAINTENANCE
• Ensure the Power Switch on the transformer unit is ON when you want to charge the battery with AC mains.
• Check the nominal battery voltage is 12VDC.
• Ensure there is space (10cm each side) beside the PM235J unit for the appropriate ventilation.
