Page 34: Pv Input Fuses Blown
Isolated SmartSolar MPPT RS Under normal operating conditions, the small black flag on top of the relay should be in the "OK" position. Additionally, a green LED on the PCB will be lit, indicating that the safety circuits are actively monitoring for hazardous situations. If the SmartSolar MPPT RS is powered on and active, but the green LED is not lit, it indicates that the safety circuits have been triggered. -
Page 35: Solar Charger Externally Controlled
Isolated SmartSolar MPPT RS 6.4. Solar charger externally controlled The solar charger can be controlled by an external device. The external device can stop or reduce the charge current to the battery. This is not a fault but expected behaviour. Managed batteries or an inverter/charger with an external control system like, for example, an ESS system, can control the solar charger via a GX device. -
Page 36: Batteries Are Not Being Charged
Isolated SmartSolar MPPT RS 6.5. Batteries are not being charged This chapter describes situations where the charger is active, but the batteries are not being charged. The VictronConnect app indicates that the charger is active and the charge voltage is correct, but the charge current is zero, or close to zero. There are a number of reasons why this can happen, namely: •... -
Page 37: Battery Not Connected
Isolated SmartSolar MPPT RS 6.5.2. Battery not connected For the solar charger to be able to charge the battery it needs to be connected to the battery. It might look like the battery is connected because the solar charger is able to operate without a battery connected and the VictronConnect app will show a battery voltage and a charge stage, but the charge current is zero or close to zero. -
Page 38: Battery Settings Too Low
Isolated SmartSolar MPPT RS 6.5.3. Battery settings too low • In the VictronConnect app, navigate to the solar charger "Settings" menu and select the "Battery" menu. • Check if the "Max. charge current" value is set correctly and corresponds with the battery manufacturer's recommendation. •... -

Page 40: Wrong Temperature Compensation Setting
Isolated SmartSolar MPPT RS Measure the battery voltage on the terminals of the battery using a multimeter. Compare the two voltages to see if there is a voltage difference. 6.6.4. Wrong temperature compensation setting If the temperature compensation coefficient is set incorrectly, the batteries can be undercharged or be overcharged. The temperature compensation can be set via VictronConnect or via a display. -
Page 41: Pv Problems
Isolated SmartSolar MPPT RS A battery contains a number of cells that are connected in series. When a battery is old or has been damaged, a likely scenario is that one of these cells is not operational anymore. When the faulty battery is charged, the damaged cell will not accept charge and the remaining cells will receive the broken cell’s charge voltage and thus will be overcharged. -
Page 42: Full Rated Output Not Reached
Isolated SmartSolar MPPT RS The VictronConnect App can be used to see what the maximum PV power was for any of the last thirty days. This information could be used to diagnose problems with less than expected PV power or daily yield. 6.8.2. -
Page 43: Pv Voltage Too High
Isolated SmartSolar MPPT RS For more information on system grounding, see the "System grounding" chapter in the Wiring Unlimited book. The SmartSolar MPPT RS connection between PV DC and battery DC is fully galvanically isolated. 6.8.8. PV voltage too high The PV voltage should never exceed the maximum rated PV voltage of the solar charger. -

Page 45: Error Code Overview
Isolated SmartSolar MPPT RS 6.10. Error code overview The error codes are displayed on the VictronConnect app, display or connected GX device. For the most up-to-date version of this list see this link: https://www.victronenergy.com/live/mppt-error-codes. Note that not all of these errors might apply to your product. Some error types only apply to solar chargers, DC-DC chargers or AC chargers or are specific only to certain models within a charger group. - Page 46 Isolated SmartSolar MPPT RS Error 21 - Current sensor issue • The current measurement is out of range. Disconnect all wires, and then reconnect all wires, to make the charger restart. Also, make sure the minus on the MPPT charge controller (PV minus/Battery minus) is not bypassing the charge controller.
- Page 47 Isolated SmartSolar MPPT RS Multi (connected to the grid): • The ground wire in the installation is not present or not connected properly. • Line and Neutral are swapped in the installation. This error will not auto-reset. Check the installation and restart the unit using the power-switch. Error 50, Error 52 - Inverter overload, Inverter peak current •...
- Page 48 Isolated SmartSolar MPPT RS Our Chargers and Solar Chargers automatically configure themselves to be BMS-controlled when they are connected to one; either direct or via a GX Device. And that setting is semi-permanent: power cycling the charger will not reset it. When removing charger from such system, and reusing it in a system without BMS, that setting needs to be cleared.
- Page 49 Isolated SmartSolar MPPT RS Error 119 - Settings data lost • The charger cannot read its configuration, and stopped. This error will not auto-reset. To get it working again: First, restore it to factory defaults. (top right in Victron Connect, click on the three dots) Disconnect the charge controller from all power-sources Wait 3 minutes, and power up again.
