Most portable power stations sit in a garage waiting for a blackout. The PowerMax 2400 Pro refuses to be idle. With a built-in 800W microinverter, it plugs into balcony solar panels and feeds surplus power back into your home grid, trimming your electricity bill every sunny day. When the grid drops, it switches to backup mode in milliseconds. It earns its keep whether the lights are on or off.
2016Wh That Grows With You
The base unit carries 2016Wh of LiFePO4 capacity. Stack additional BP2400 Pro battery packs via OSCAL's cableless stacking design — no cables, just snap and click — and scale up to 22,176Wh. At roughly 6.3 kg per module, moving pieces one at a time is practical even for a single person. The full stack covers over a week of household power for essentials.
LiFePO4 chemistry means 3,500+ cycles to 80% capacity. If you cycle once daily, that is roughly a decade before meaningful degradation.
2400W Output, 4800W Surge
The pure sine wave inverter pushes 2400W continuous with 4800W surge headroom. That covers refrigerators, freezers, microwaves, power tools, CPAP machines, and 99% of household appliances. Sixteen output ports — four AC, two 100W USB-C, four USB-A, DC5521, car outlet, Anderson connector, and a wireless charging pad in the lid — mean no one fights over a charging port during an outage.
The Balcony Solar Difference
The built-in 800W microinverter is what separates the 2400 Pro from every other power station in its class. Connect a pair of balcony solar panels, and the system operates in three modes:
- On-grid: Solar charges the battery, surplus flows to your home circuits, reducing grid consumption in real time - Off-grid: Battery powers your devices independently, no grid connection needed - Hybrid: Grid and solar work together, with the microinverter prioritizing solar and drawing from the grid only when necessary
OSCAL estimates up to 1,095 kWh of solar generation per year — roughly 28.8% more than comparable balcony systems — translating to about €490 in annual electricity savings. Your actual numbers depend on panel orientation and local sunlight hours, but the math is straightforward: every watt-hour from the sun is a watt-hour you do not pay the utility for.
Dual Speakers That Actually Sound Good
A 25W subwoofer paired with a 10W tweeter pushes 130dB. That is loud enough for outdoor movie nights, campsite music, or emergency signaling across a 100-meter range. Most power stations treat a speaker as an afterthought — a tinny buzzer for alerts. The 2400 Pro treats it as a feature, and the difference is immediately obvious the first time you play music through it.
Fast Charging, Smart Control
AC input at 1500W charges the battery to 80% in approximately 1.2 hours. Solar input maxes at 800W through the built-in MPPT controller. Dual charging (AC + solar) cuts total charge time further. WiFi and Bluetooth connect to OSCAL's app for real-time monitoring, output toggling, and energy tracking from your phone.
The on-unit display shows the essentials at a glance, so you are not dependent on the app for everyday operation.
Safety and Build
The Battery Management System monitors voltage, current, and temperature in real time with eight layers of protection: over-current, short-circuit, over-voltage, under-voltage, over-temperature, low-temperature, over-charging, and overloading. The enclosure is built for indoor and covered outdoor use, though it lacks the full IP rating of OSCAL's rugged 3600 series for extreme weather exposure.
A 5-year warranty backs the unit, and OSCAL's European service network handles repairs locally.
Who It Is For
If you live in an apartment with a balcony and want to cut your electricity bill without complex installation, the PowerMax 2400 Pro on the OSCAL Store is purpose-built. If you want backup power that does more than gather dust between outages, the microinverter means the system works for you every day.
For pure portable use without the solar integration, the PowerMax 2400 drops the microinverter and dual speakers at a lower price. For whole-home backup with 240V split-phase output, step up to the PowerMax 6000.
