This panel can also collect light from the back. To avoid an optimistic result, our calculation only counts its rated 220W front side.

How are the strings connected?

Panels in a string are connected in series. The calculation distributes identical strings across the station’s modeled inputs; extra strings on one input are parallel. This is not a wiring diagram.

Only identical panels and equal string lengths are modeled. Fuses, cable gauge, grounding and local installation rules need a separate check.

DELTA 3 Plus

11–60 V · 15 A per input

Why this result?
Charging voltage
18.4 VLimit: 11–60 VWithin limit
Voltage in cold weather
24.3 VLimit: < 60 VWithin limit
Current per used input
12 ALimit: ≤ 15 AWithin limit
Power per used input
220 WLimit: ≤ 500 WWithin limit

Two independent 11–60V inputs; each accepts 15A and 500W, for 1,000W total.

Short-circuit current (Isc): 13 A per used input. Still verify protection and wiring requirements.

Calculation assumes: 1 identical strings across 1 used input(s).

Cable route — not yet verifiedMC4 → XT60i

Check the exact adapter, polarity, fuses and cable ratings in both manuals.

Modeled power ceiling: 220 W. A limit, not a forecast of solar yield or permission to connect.
