A complete solar generator kit for home backup: the Oscal PowerMax 6000 with 6,000W of 120V/240V output and 3,600Wh of LiFePO4 storage, plus two 400W foldable PM400 Plus panels to recharge it from the sun when the grid is down.
To run both panels at once you need an MC4 parallel Y-branch connector, sold separately. Either panel also works on its own without one.
Keep the House Running Through a Long Outage, Recharged by the Sun
The Oscal PowerMax 6000 + 2x PM400 Plus bundle is a solar generator kit for home backup and off-grid power. It pairs a 6,000W pure sine wave power station with a 3,600Wh LiFePO4 battery and two 400W foldable solar panels (800W combined). The station supplies 120V and 240V, including a 30A 120/240V twist-lock outlet, recharges from a wall outlet in about two hours, and on a clear day the two panels can put back roughly 2.5 to 3 kWh. Because it burns no fuel, it can run indoors in a garage, basement or utility room. Both panels share the station's single XT-60 solar input, so running them together needs an MC4 parallel Y-branch connector, sold separately. Capacity expands to 57.6kWh with up to 15 BP3600 battery packs.

Why a solar kit beats a gas can in a long outage
A gas generator gets you through the first night of an outage. The trouble starts on day two, when the stations are closed, the cans are empty and it is not safe to run the engine anywhere near the house. This kit is built for that second day and the days after it.
The PowerMax 6000 stores 3,600Wh in LiFePO4 cells rated for 3,500 cycles to 80% capacity, and delivers it as 6,000W of pure sine wave power at 120V and 240V. That covers the refrigerator, freezer, lights, internet, a CPAP and the phone chargers at the same time, with room left for a window AC or a 240V tool.
Then the panels go out on the deck or the lawn. Two 400W PM400 Plus panels unfold to about 7.6 feet each and, in good sun, harvest roughly 2.5 to 3 kWh a day. That is enough to replace most of what a fridge, lights and electronics use overnight, so a careful household can keep going as long as the weather cooperates, with no fuel to buy and no engine to start.
When the grid comes back, the system stays useful: plug it in and it refills from the wall in about two hours, add BP3600 packs when you want more storage, and take it to the cabin or the campsite the rest of the year.

Runtimes are estimates that assume about 85% of the 3,600Wh battery reaches your appliances. Real results depend on the appliance, how often it cycles, temperature and what else is running. Solar figures depend on season, location, panel angle and shade. Check your appliance labels before planning around a number.

Is this kit right for you?
Best for
- Homeowners in hurricane, ice storm and wildfire shutoff areas who plan for outages that last days
- Households that need a refrigerator, CPAP or home office to keep running without a gas generator
- Anyone who wants backup power that can sit in a garage or basement with no fumes or noise
- Rural properties and cabins that want 240V and a solar recharge in one kit
- Buyers who want to start with one battery and add storage later
Not the right fit for
- Whole-home backup with central AC: that needs a home standby generator
- Anyone who wants automatic, hands-off switchover: this is a portable system you connect yourself
- Carrying by hand: the station weighs about 101.7 lb and each panel about 37.5 lb
- Running both panels without buying an MC4 parallel Y-branch connector

Safety and setup
LiFePO4 cells
Lithium iron phosphate is the stable lithium chemistry used for home storage, rated here for 3,500 cycles to 80%.
No combustion, no carbon monoxide
Nothing burns, so the station can sit indoors near where you live and sleep.
Built-in protections
Over-voltage, overload, over-temperature, short circuit, low-temperature, low-voltage and overcurrent protection.
Connect panels in parallel
Join the two panels' MC4 leads with a parallel Y-branch connector rated for about 22A. Parallel keeps the voltage at one panel's 47.52V open-circuit level.
Know the temperature limits
The station discharges from 14 to 113°F and charges from 32 to 113°F. Panels operate from 14 to 149°F.

Frequently asked questions
Can the Oscal PowerMax 6000 solar generator kit power my house during an outage?
It can run the essentials: refrigerator, freezer, lights, internet, a CPAP and small appliances, with 6,000W of 120V and 240V output. It is not sized for central air conditioning. Its 30A 120/240V twist-lock outlet is the style many home generator inlets and transfer switches use; a licensed electrician should make any connection to your home's wiring.
How long does it take to recharge with the two 400W solar panels?
The two panels are rated for 800W combined. In strong sun they typically put back about 2.5 to 3 kWh over a day, which is most of the 3,600Wh battery. From a wall outlet it recharges in about two hours at up to 1,800W.
Do I need anything extra to use both panels at the same time?
Yes. The PowerMax 6000 has one XT-60 solar input and the panels have MC4 connectors, so join the two panels with an MC4 parallel Y-branch connector, then connect them to the station's XT-60 input. The Y-branch is sold separately and widely available online; choose one rated for about 22A. Either panel works on its own without one.
Can I run it inside my house?
Yes. It is a battery system with no engine, so it produces no exhaust or carbon monoxide and can run in a garage, basement or utility room. Keep it within its 14 to 113°F discharge range.
How long will it run a refrigerator?
A typical full-size refrigerator averages 100 to 150W, so the battery alone runs it for roughly 20 to 30 hours. With the panels recharging during the day, it can keep a fridge going for as long as the sun holds up.
Can I add more battery capacity later?
Yes. The PowerMax 6000 accepts up to 15 BP3600 expansion packs, sold separately, for up to 57.6kWh in total.
Does it put out 240V?
Yes. The station supplies both 120V and 240V, with 240V available through its 30A 120/240V twist-lock outlet.
Which products make up this bundle?
One Oscal PowerMax 6000 power station and two Oscal PM400 Plus 400W foldable solar panels. The MC4 parallel Y-branch connector for running both panels together is sold separately.
