communication protocol.
4. PV Input Mode
PV input mode selection: WKS Iinverter has 2 MPPT channels. The 2 MPPT can operate independently, also can
operate in parallel. If the PV strings are connected in parallel outside the inverter, you should choose the “in parallel
mode”, otherwise use the default setting (independent mode).

***S()
1)
If PV generation > LOAD consumption (ΔP > 100W),
WKS I inverter will charge battery.
2)
If PV generation = LOAD consumption, WKS I
inverter wont’ charge or discharge battery.
3)
If PV generation < LOAD consumption (
Δ
P
＞
100W), WKS I inverter will discharge battery.
4) If PV generation is normal,but LOAD consumption=0,
the surplus power will be stored in the battery.
