Solar generator kits · 481Wh to 2,400Wh
A kit is one power station plus one foldable solar panel, bought as two items: 481–2,400Wh of storage, 600–3,300W of AC output and a 220W or 450W panel. In the US the same thing is usually called a solar generator — there is no engine and no fuel behind the name, just a battery and the panels that refill it. Four tiers, one per job — camping, the 1,000W class, high-draw portable work, and a modular system you can grow.
Entry
Weekend campers, CPAP users without a humidifier, and photographers — anyone who needs one night of power and wants it back before the next one.
220W against a 240W ceiling
3.0–3.4 hours to full · clear midday sun
Clear midday sun. Overcast pushes this past 13 hours, which is why the P600 keeps AC charging as its primary route.
1000W class
Home outages, CPAP backup and mobile work — the 1kWh class, with the panel that actually refills it inside one afternoon.
450W label against a 400W input — real output is 340–385W, so nothing is lost
3.6–4.0 hours to full · clear midday sun
The 450W panel is what puts this class inside one afternoon; a 220W panel takes 7.1–8.2 hours on the same station.
High-power portable
Contractors, van builds and long off-grid stays that need 2,400W of AC and can wait two sun-days for a full bank.
450W against a 1,200W ceiling — voltage, not watts, is the limit
6.7–7.6 hours to full · clear midday sun
Two sun-days for a full bank. Plan AC charging as the turnaround and solar as the daytime offset.
Modular entry
Power-tool users who want 3,300W now and the option to stack 2.4kWh modules later instead of replacing the station.
450W / 42.02V inside 1,000W / 100V
7.4–8.4 hours to full · clear midday sun
Two SP450s in series bring the same bank to roughly 3.7–4.2 hours if a one-day refill matters.
Recharge times are the published figures from each panel page — this page does not re-derive them. The total is the station price plus the panel price: there is no bundle discount, and no bundle markup either.
The 1000W on the label is AC output, not storage. In this class the battery is about 1kWh, and the output has already moved past 1,000W — the P1200 in the second card is 1,152Wh and 1,200W, while the units it is priced against now quote 1,500–2,000W. Output decides whether an appliance starts; capacity decides how long it runs. Sizing off the wattage alone is how people end up with a 1000W station that dies in three hours.
The bigger difference is the panel. A 1kWh bundle usually pairs the station with about 200W of folding panel, which needs six hours of good sun for a full battery. This kit ships 450W, so the same 1,152Wh lands in 3.6–4.0 hours — one afternoon instead of most of a day. When two listings look identical on the station spec, that is the number that separates them.
The four stations from the kits above, against every panel configuration those stations accept. Watts are nameplate totals for the whole string; volts are the summed open-circuit voltage, which is what a station actually sees before its controller starts drawing. The star marks the pairing each kit ships with.
| Power station | Battery | Solar input | 1 × SP220 220W · 21.06V | 2 × SP220 series 440W · 42.12V | 1 × SP450 450W · 42.02V | 2 × SP450 series 900W · 84.04V |
|---|---|---|---|---|---|---|
| P600 | 481Wh | 240W 12–50V / 12A | Fits | Clipped | Clipped | Over voltage |
| P1200 | 1,152Wh | 400W 12–60V / 12A | Fits | Clipped | Clipped | Over voltage |
| P2400 | 2,160Wh | 1,200W 12–60V / 25A | Fits | Fits | Fits | Over voltage |
| G2400 | 2,400Wh | 1,000W 11–100V / 20A | Fits | Fits | Fits | Fits |
"Clipped" means the station stops accepting at its ceiling: the panels still work, you just pay for watts that never arrive. "Over voltage" means the string exceeds the input window and should not be connected. Each verdict is a voltage and wattage check, because a series string keeps the single-panel current; current still binds on the input side, where one SP220 draws 12.22A at STC against the 12A input on the P600 and runs 9.2–10.6A in real light. The starred 450W cell on the P1200 reads Clipped on the same nameplate-versus-reality logic — 450W of label against a 400W input — while the panel's real 340–385W lands underneath that ceiling, so nothing is lost in practice. Parallel wiring is a separate case — two SP220s in parallel pull 24.44A, above the 12A input on the P600 and the 20A input on the G Series, so only the P2400's 25A input clears it and a parallel array elsewhere needs its own controller. The full electrical data and the series-versus-parallel table sit on each panel page: 200W / 220W panel and 400W / 450W panel.
Work backwards from what you burn, not forwards from what the battery holds. Three steps, plus the factor of 1.5 that covers the gap between a panel's label and what actually reaches the battery.
Watts × hours for every device, then sum. A mini fridge averaging 60W over 24 hours is 1,440Wh; a laptop at 60W for four hours is 240Wh.
Four hours is the planning figure for most of the continental US, five on the Gulf coast and in the desert Southwest, three in a northern winter. That division gives the watts the array has to deliver while the sun is strongest.
Only about two thirds of a panel's rated watts reaches the battery once heat, angle, soiling and charging losses are counted, so the nameplate figure is 1.5× what step two produced. Then compare it with the station's solar input ceiling and take the lower number — anything above the ceiling is money spent on watts that never arrive.
| Scenario | Typical load | Daily use | Array must deliver | Panel to buy |
|---|---|---|---|---|
| Camping | Lights, phone, camera, laptop | 500Wh | 125W | 1 × SP220 (220W) |
| Home outage | Fridge, router, lights, phones | 1,200Wh | 300W | 1 × SP450 (450W) |
| RV / cabin | Fridge, coffee, router, TV | 3,000Wh | 750W | 2 × SP450 (900W) |
500Wh a day divides to 125W of array, and 1.5× that is 188W — which is why the entry kit ships with the 220W SP220. 1,200Wh a day lands on 300W, 450W with the factor, and that is the SP450. 3,000Wh a day asks for 750W, or 1,125W on the label; no G Series main base accepts more than 1,000W, so the answer caps at two SP450s and the AC charger covers the shortfall.
Kit questions
Which kit to pick, buying separately, mixing brands, cloud cover and what the hour figures really mean.
Start with the P1200 kit — 1,152Wh, 1,200W and a 450W panel, 3.6–4.0 hours to full. It is the tier that sits in the 1kWh class, which is what most listings mean by a 1000W station. Move up to the P2400 kit when an appliance needs more than 1,200W of output; move down to the P600 kit when a weekend of lights, cameras and a laptop is the whole job. What separates a good combo from a cheap one at this size is the panel: 450W refills in an afternoon, 100W takes two days.
No, and the two numbers answer different questions. 1000W is AC output — whether an appliance will start at all. 1000Wh is storage — how long it keeps running. The P1200 is 1,152Wh and 1,200W, which is what this class usually means in practice, while a 1000W unit with 500Wh of battery starts the same appliances and runs them for half as long. Check both numbers before comparing prices.
The P1200 kit takes 3.6–4.0 hours of clear midday sun with its 450W panel. The station accepts 400W, and the panel's real output is 340–385W, so it lands just under the ceiling and nothing is wasted. Swap in a 220W panel on the same station and the wait roughly doubles to 7.1–8.2 hours.
Yes. Every item on this page is its own SKU — there is no bundle packaging and no bundle price. A kit is our recommendation of which panel goes with which station, and the cart simply shows two lines instead of one.
As long as the string stays inside the station's voltage window and the total stays under its watt ceiling. A G Series main base accepts 1,000W at 11–100V, so two SP450s land at 900W and 84.04V with room to spare — the modular kit is the one tier where a second panel is a real option later. The P600 caps solar at 240W, so a second panel there would be wasted money. The pairing matrix above covers every combination.
Usually yes, if its open-circuit voltage sits inside the station's input window and its current stays under the amp limit. Both panels ship with MC4 connectors on a factory lead plus an adapter cable covering DC5521, Anderson, XT60 and aviation M16. Check Voc first — a string that exceeds the window can damage the charge controller, not just underperform.
The SP220 returns 165–190W in clear midday sun, 65–110W under thin cloud and 10–45W in flat overcast. The SP450 goes 340–385W, 135–225W and 20–90W across the same three conditions. Output never stops, but below thin cloud neither panel refills a station within a single day — that is when the AC charger earns its place.
No. Every SoreinPower station has a built-in MPPT controller, so the panel connects straight to the solar input. A separate controller only enters the picture when you wire panels in parallel: two SP220s in parallel pull 24.44A, over the 12A input on the P600 and P1200 and the 20A input on the G Series — only the P2400's 25A input clears it.
No, that figure is equivalent full-sun hours, not clock hours. A clear day delivers four to five of them in most of the continental US, so 7.4–8.4 equivalent hours is most of two calendar days. Only the entry kit at 3.0–3.4 hours actually finishes inside one day.
