Batteries Are Not Charging

Start with the available charging power, site demand and any alarms. A battery can show little or no charging even when solar panels or a generator are producing power. The system may be supplying loads first, holding a reserve, following a schedule or applying a battery limit.

Check the readings together

Confirm the monitoring timestamp is current. If the app is offline, use the accessible local display.
Record the battery percentage, solar production, site load and grid or generator input at the same time.
Check the battery and inverter for messages or active alarms.
Note the time of day, weather and whether shading or cloud has reduced solar production.
Check the operating mode against your MyEnergy handover. A charging schedule may intentionally prevent grid charging outside its configured window.

Look at power available after loads

If the property is using most of the available power, little may be left to charge the batteries. Reduce non-essential large appliances using their normal controls and observe the trend. Do not expect an immediate percentage change from a short observation.

On generator systems, a running engine does not by itself confirm that the inverter is accepting generator power. Record the input shown on the display and any generator or inverter message. Use the site’s generator instructions; do not adjust electrical output settings yourself.

When slower charging can be normal

The battery is approaching full charge.
An AGM or gel bank is in absorption or float.
The battery management system is limiting charging for temperature or cell conditions.
The system is operating to a configured reserve or charging schedule.

These are possibilities to check, not a diagnosis. Persistent alarms, prolonged loss of charging or a major change from normal operation need assessment.

Safe checks only

From a safe position, note whether an external indicator or labelled switch appears different from normal. Do not operate isolators, reset breakers, remove covers, disconnect cables or change charging settings without the procedure for your installation. Do not connect an external charger to recover a battery.

When to contact MyEnergy

Contact us promptly if the bank is deeply discharged, the system repeatedly shuts down, a module is unavailable, an alarm persists, or the generator/grid input appears available but charging does not resume as expected. For smoke or fire, move away and call 000.

Submit a support request with your site, battery and inverter models, alarm photos, recent changes and the readings above. Call 1300 706 870 if you need help identifying the next step.
