 Follow below procedure only if (a) the charger is not measuring any PV voltage when it should (i.e. during the day, with sun shinning, and all connections are ok). (b) the charger no longer charges the battery and measuring the PV Input with a MultiMeter in resistance mode shows a few Ohms or lower. (c ) the charger no longer charges an error 80 to 87 is/was shown.

+==== Reset procedure ====
 To recover from such failure, the below reset procedure must be followed.
   - Disconnect the PV Input terminals.
-  - Power the solar charger through its battery terminals with a 12V battery or bench power supply set to 12V.
+  - Power the solar charger through its battery terminals with a **12V** battery or bench power supply set to **12V**. Note that if the voltage at the solar charger battery terminals is higher than 15V, reset button is disabled in VictronConnect so the reset procedure won't be possible.
   - Make sure no error 80 to 83 is active. If it is active, power cycle the unit.
   - Open VictronConnect and navigate to the Product settings menu. There the PV Short reset feature is shown.{{ :drafts:mppt_pv_short_relay_reset.png?600 |}} Note that the feature only shows when (a) the connected units features the protection, ie. 250/100 VE.Can model, HQ2150 and later; (b) requires the battery voltage to be between 10 and 15V; (c ) requires VictronConnect v.580 or later; (d) requires firmware version v3.12 or later to be installed on the Solar Charger and (e) no error 80 to 83 is active.
