Port 1: max 1600W
Port 2: max 1000W
2600W is the combined maximum, not per port
You can use one or both ports at the same time, but:
You can't exceed 1600W on the first port
You can't exceed 1000W on the second port
You can't exceed 2600W total
Using 400W solar panels
In perfect conditions:
400W per panel
2600 ÷ 400 ≈ 6.5 panels
So realistically:
6 × 400W panels = 2400W (ideal)
7 panels = 2800W (exceeds max, extra power is clipped)
A common setup would be:
4 panels (1600W) on the 1600W port
2 panels (800W) on the 1000W port
Total ≈ 2400W
How long will it take to charge?
That depends on the battery capacity, but assuming a large ~4000Wh power station:
Best-case math (theoretical):
4000Wh ÷ 2400W ≈ 1.7 hours
Real-world expectations:
Solar usually delivers 60–75% of rated output
Losses from heat, angle, wiring, clouds, and charge tapering
So in practice:
2400W of panels ≈ 1400–1800W actual
Expect roughly 3–4 hours of strong sun for a full charge
Bottom line
2600W is the maximum solar the unit can accept, not what panels automatically provide
With 400W panels, 5–6 panels is the sweet spot
Real-world charging takes hours of good sunlight, not minutes
Panel voltage and current limits matter just as much as wattage when wiring
