Nature's Generator Folding 400W Solar Panel, Monocrystalline, with Steel Stands

The Nature's Generator Folding 400W Solar Panel is a monocrystalline panel at 23% efficiency with built-in steel stands and an IP67 rating. It folds to 38.3" × 24" × 3.4" at 17 lbs and pairs with the Nature's Generator L3600 and L6000.

Charge time per station (RPC estimate, full sun, panel at 75% of rating, about 300W each):

Each panel is 39.77V open-circuit. On the L6000, connect one panel per solar input; two in series would exceed its 60V limit. On the L3600, two in series reach 79.5V, right at its limit of about 80V, so ask us before running two in series in freezing weather.

Size it for your own setup: pick your appliances, days off-grid and solar in the RPC Power Calculator, and it shows the in-stock stations and kits that fit.

Steel stands set the angle, and a storage pocket keeps the MC4 leads and junction box tidy. The panel has a fixed 150cm (4 ft 11 in) 12AWG MC4 lead. To reach an L3600 or L6000, Nature's Generator pairs it with its MC4 to Anderson 50 ft solar panel cable, sold separately.

Best for: Portable solar for L3600 and L6000 systems • RV and campsite charging • Storm prep you can store in a closet

Not the best fit if: you want a permanent array. For roof or ground mounting, look at the 440W bifacial panels. For a lighter panel, look at the 200W folding panel (13.2 lbs).

Works with: L6000 power station • L3600 power station • L6000 Power Pod • L6000 solar generator kit

Frequently Asked Questions

How much power does a 400W panel really make?
About 300W in full midday sun angled at the sun, and roughly 1.5kWh over a good solar day.

How many can I connect to an L6000?
One per solar input, so two on one L6000. Two in series would exceed its 60V input limit.

Is it waterproof?
It's rated IP67 for rain and spray. Keep the connectors out of standing water.

Which cable do I need?
The panel has a fixed 150cm (4 ft 11 in) MC4 lead. Nature's Generator lists its MC4 to Anderson 50 ft solar panel cable to connect it to a station, plus MC4 extension and branch cables for longer runs or two panels. All are sold separately.
