What causes E027 error on SolarMax Inverter (BATTERY overcurrent)?
If your SolarMax Inverter displays error E027, it means there is BATTERY overcurrent. Check the sizing and connections at the BATTERY inputs.
What to do if my SolarMax ES-T shows a E011 error (high grid voltage)?
If your SolarMax Inverter displays error E011, it means there's high grid voltage. Verify that the mains voltage is within the range allowed by local regulations and check the network impedance. If the mains voltage is outside the permitted range due to local grid conditions, contact the grid operator to explore voltage adjustments or request approval for changes to operating limits. If the mains voltage is within the allowed range, but the alarm persists, further investigation is needed.
What to do if my SolarMax ES-T displays a E013 error (low grid voltage)?
If your SolarMax Inverter shows error E013, it indicates low grid voltage. Ensure that the mains voltage is within the range allowed by local regulations and examine the network impedance. Should the mains voltage fall outside the permitted range due to conditions of the local grid, contact the grid operator to discuss adapting the voltages at the connection point or to request approval for changing the operating limits. If the mains voltage is within the allowed range, but the alarm continues, further investigation is needed.
What does E015 error mean on SolarMax Inverter (high grid frequency)?
If you're seeing error E015 on your SolarMax Inverter, it signifies high grid frequency. Make sure the grid frequency is within the range allowed by local regulations. If the grid frequency exceeds the permitted range due to local grid conditions, contact the grid operator to request approval for changing the operating limits. If the grid frequency is within the allowed range, but the alarm persists, further investigation is needed.
Why is my SolarMax ES-T showing E028 error (Battery not recognized)?
If your SolarMax Inverter shows error E028, the battery is not recognized. Check the connections and polarity at the BATTERY inputs. Also, check the battery voltage and make sure it is within the limits allowed for operation.
What does E037 error mean on SolarMax ES-T?
If your SolarMax Inverter displays error E037, it indicates a converter control system fault. You should switch off and restart the system.
What does E017 error mean on SolarMax ES-T (high grid frequency)?
If you're seeing error E017 on your SolarMax Inverter, it signifies high grid frequency. Make sure the grid frequency is within the range allowed by local regulations. If the grid frequency exceeds the permitted range due to local grid conditions, contact the grid operator to request approval for changing the operating limits. If the grid frequency is within the allowed range, but the alarm persists, further investigation is needed.
What does E018 error indicate on a SolarMax Inverter (low grid frequency)?
If your SolarMax Inverter displays error E018, ensure that the grid frequency is within the range allowed by local regulations. If the grid frequency is not within the permitted range for reasons due to the local grid conditions, contact the grid operator to request approval for the change to the operating limits. If the grid frequency is within the allowed range, but the alarm persists, further investigation is needed.
What does E038 error mean on SolarMax ES-T Inverter?
If your SolarMax Inverter displays error E038, it indicates a converter control system fault. You should switch off and restart the system.
What to do if SolarMax ES-T shows E005 error?
If your SolarMax Inverter shows error E005, it indicates a faulty protection interface device integrated in the system. You should switch off and restart the system.
