About Charging is displayed without photovoltaic panel connected
Yesterday I found out the problem charging my two 12v 250ah lead acid batteries was due to wrong wire connection from my PV panels not my 40A Hqst Mppt Solar controller (same as Epever Tracer AN 40). The batteries were eventually charged fully and the battery icons in both, the controller and the 3,000watt Edecoa Inverter LCD show full charge .

The solar charger is unresponsive (inactive) if the display is not illuminated, there is no charging activity, and it is not communicating with the VictronConnect app via Bluetooth or the VE.Direct port.
SCC were not damaged by disconnecting the battery with the panels left connected. Connecting the battery first is so the SCC recognises the battery as 12 or 24 volts etc.
You can't connect/disconnect the load, you can't measure the current flowing to the load, and also the charger is "fooled", since current drawn by the load is seen as charging current flowing into the batteries.
Solar or photovoltaics (PV) provide the convenience for battery charging, owing to the high available power density of 100 mW cm −2 in sunlight outdoors.

6 FAQs about [Charging is displayed without photovoltaic panel connected]
Why is my solar charger not charging?
There are a number of reasons why this can happen, namely: The battery is full, and no more current is needed. The solar charging is not connected to the battery (cable, fuse or circuit breaker issues). Wrong configuration (voltage or current set too low). The charger is externally controlled (ESS or DVCC).
Why does my solar charger only show voltage and power readings?
If the solar charger only shows voltage readings and omits current and power readings, it indicates that the current monitoring is bypassed due to a potential PV negative being mistakenly connected to the battery negative. To rectify this, make sure to connect the PV negative to its respective terminal instead of the battery negative. 8.11.2.
How do I know if a battery is a photovoltaic?
Display Charge Current: Check out the charge current from the photovoltaic (PV) system to the battery. It’s typically displayed on the settings menu, giving you an insight into the power flowing into your battery. Select Battery Type: Next, go to the Battery Type Selection setting.
What happens if a solar charger is unable to turn off?
If the solar charger is unable to turn off the PV input, it will go into a safe mode in order to protect the battery from over-charging or having a high voltage on the battery terminals. In order to do that, the solar charger will stop charging and disconnect its own output. The solar charger will become faulty. 8.12.12.
Why does a solar charger show a battery error?
This is a safety mechanism, the reason to still enable the output is to allow a system to self-recover from a battery low situation. Solar Chargers only show this error when there is solar power available and thus the device is ready to initiate charging.
How do I check the voltage of my solar charger?
Use the VictronConnect app, a solar charger display or a GX device to check the battery and PV voltage. If the above step is impossible, use a multimeter in DC mode to measure the battery and PV voltages at the solar charger terminals. WARNING: Certain solar charger models may have PV voltages up to 250Vdc.
