accreditation, as required by local authority.
Do NOT put explosives or flammable materials, e.g. gasoline, kerosene, diesel, oil, wood slab, cotton, or rag
close to batteries or WKS I inverter.
Disconnect AC connection first, then disconnect battery & PV(PV1&PV2), then wait at least 5 minutes
(discharge capacitors) before maintenance to prevent electric shock.
WKS I inverter shall be disconnected completely (BAT, PV & AC) while being maintained.
WKS I inverter can be very hot during working. Switch off WKS I inverter & wait WKS I inverter to cool

airtight or badly ventilated place or cabinet. This can be very harmful to system performance & service life.
Keep WKS I inverter/batteries away from direct sunshine. Don’t put WKS I inverter/batteries close to a
furnace or fire. The can lead battery to leak even explode.
The current capacity of DC power cables (from battery to inverter) should be at least 90A. Use short DC power
cables to avoid high voltage drop & power loss.
Use a multimeter to check the batter voltage & polarity before switching ON batteries. Make sure connections
are correct according to this manual.
Use a multimeter to check the PV voltage & polarity before switching ON PV isolator. Make sure connections
are correct according to this manual.
