OPERATIONAL PROBLEMS
Q: MPPTsolid is not producing the expected output power.
A: Are the PV panels shaded by clouds or structures? Clouds, shade and dirty panels can
cause lower than expected performance from the solar arrays.
Is the current limit on either the input or output set lower than needed for the efficient
operation of the charger?
Are the batteries fully charged? If so the MPPTsolid will only trickle charge the batteries to
maintain a full charge. In this instance the charger cannot use the maximum output from
the PV array.
Q: Batteries are hot, and/or out gassing.
A: Check that the BTS (battery temperature sensor) is installed and connected to the
batteries properly; if this is the case, there may be a defect in the charger unit itself.
Contact Phocos for assistance.
A: Check that battery charging parameters are correct using PowerWizard software.
Q: Cables from the charger to the batteries are hot.
A: The size (AWG) of the cables may be under sized for the current. Check that the size or
distance of the wire run is within the guidelines of the NEC.
Make sure the breakers/fuses are the correct sizing to handle the current. Check for a
short in the PV wiring if it is the PV breaker.
Q: Erratic behavior of the charger unit.
A: Check that the PV arrays are balanced for voltage, ie. that all the arrays are wired to
supply the charger with the same voltage. Arrays of different voltages are not tolerated
