GFDI fuse is blown, the fault in PV array or wiring must be found and GFDI fuse replaced. For
fuse replacement, see section 4 “Power, GFDI and Error LED Indicators”.
Inverter over heating and power de-rating. If the power output is lower than normal and there is an
LED indication of power de-rating due to high temperature, check the following
•
Is the ambient air temp above 45-50
o
C?
•
Is the intake (front) louver grill or output (bottom) visibly blocked?
•
Is the unit in direct sunlight which is adding extra heat to the inverter?
Unit over heating, power de-rating, or unit not putting out power
•
Check insect screens in front louver grill on main enclosure door for clogging from dust,
pollen and debris. The louver/grill can be removed with 8 Philips screws holding it on and
insect screen can be cleaned or replaced (Solectria Renewables P/N HDW-150005-001)
•
Fan not running, blocked or slow
o
Check fan fuse inside main enclosure (1A) AC
o
Check fan relay inside main enclosure
o
Check the fan, make sure it spins freely (when unit turned off)
•
No grid sensing
o
Grid sensing fuses blown (0.5A or as labeled) AC inside main enclosure. Contact
Solectria Renewables (Do not replace fuses, as this represents an abnormal failure).
•
No LED indications when sun is shining. If grid voltage and DC (PV) voltage is present
and no response from inverter is evident
o
Verify AC & DC (PV) voltages are within proper ranges
o
Verify fuses in AC & DC (PV) disconnect (If equipped with PV Combiner) are
good
If at some point it is determined that the unit or any part of the unit should be shipped to Solectria
Renewables for repair or replacement, be sure to get an RMA# from Solectria Renewables and use
the same packing method as when it was shipped to you, or request instruction on packing and/or
packing materials from Solectria Renewables to help insure a safe shipment.
Intake Louver Vent Cleaning
With the unit off, DC disconnect off (to prevent needless ingestion of more dust), for example do
early morning or late evening so little or no energy generation is lost.
Method 1:
without removing vent, use a powerful vacuum and clean entire louver vent/screen.
Method 2:
remove vent by removing all Phil Pan #2 machine screws holding louver vent onto
inverter. Use compressed air from the back (insect screen) side of the louver vent/screen unit to
remove all debris. Re-assemble putting all screws in LOOSELY first and then tighten snug (do not
over-tighten).
