What it is, and what it is for
ROCKSOLAR 2,000 W 24 V Off-Grid Solar System with 1/3 HP DC Submersible Pump
A 24 V off-grid power system with a solar well pump built in: two 445 W bifacial panels (890 W) charge a 2.56 kWh LiFePO4 battery through a 60 A MPPT controller, the battery runs the 24 V brushless submersible pump whenever there is water to move, day or night, and a 2,000 W pure sine wave inverter gives you 120 V AC for lights, a fridge, tools or a cabin on the same bank. For a homestead, a livestock trough, a garden or a remote cabin with a well up to about 200 ft deep.
What's included:
- ROCKSOLAR 24 V 100 Ah LiFePO4 battery, 2,560 Wh, built-in BMS, 100 A continuous, 3,500+ cycles, 10-year warranty
- 2 × Hanersun 445 W bifacial monocrystalline solar panels (890 W), IP65, MC4 leads, 10-year warranty
- ROCKSOLAR 60 A MPPT solar charge controller, 100 V PV limit, 99.5% tracking, lithium and lead-acid profiles
- ROCKSOLAR 2,000 W 24 V pure sine wave inverter, 4,000 W surge, two 120 V outlets, USB
- ROCKSOLAR 24 V brushless DC submersible pump, 250 W (1/3 HP), 3 in diameter, stainless steel 304, built-in controller, 1 in outlet, 2 m lead, 5-year warranty
Mounting rails and racking are not included; they are quoted with the installation. Also budget for well pipe, a drop cable to the pump depth, and battery and PV cable.
Pump performance. Up to 1.3 m³/h (5.7 gal/min) and a maximum head of 70 m (230 ft); flow falls as the lift increases, so at 100 ft of lift expect several gallons a minute, and a 1,000-gallon trough fills in a few hours of sun. The 890 W array puts about 3 to 4 kWh a day into the battery in most of the US, roughly 12 to 16 hours of pumping, and the controller takes up to 1,440 W if you add a third panel later. Because the pump runs from the battery rather than straight from the panels, it does not stop when a cloud passes. The battery also carries about 2 kWh of household loads overnight; the inverter runs a full-size fridge, lights, a laptop and a coffee maker, though not all at once with a heater. Wiring is for reference; a licensed electrician should make the connections on a permanent installation. The pump is for fresh water only.
