    If a flag on top of the relays indicates the "C" position then it is closed. When the relays are closed the PV array is short circuited to stop PV power from entering the SmartSolar MPPT RS. The PV fuses or circuit breakers in the installation may open.

  • Page 32: Pv Input Fuses Blown

    If the fuses close to the PV input terminals are blown then the MPPT will be off. The fuses will blow if a fault has occurred inside the SmartSolar MPPT RS. In this case you should return the unit to the supplier.

  • Page 33: 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.
  • Page 34 Isolated SmartSolar MPPT RS Possible causes of a disconnected battery: • Loose or missing battery cables. • Loose cable connections or badly crimped cable terminals. • A blown (or missing) fuse in the battery supply cable. • Open (or faulty) circuit breaker in the battery supply cable.

The temperature compensation can be set via VictronConnect or via a display.

  • Page 38: 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.
