Power your home or RV completely off-grid with the PowMr 24V 4000W Solar Inverter. This pure sine wave unit delivers stable 110VAC output and includes a built‑in 140A MPPT charger. Its sleek glass‑top shell and crisp 6.25‑inch LCD display put full energy management in your hand. Dependable daily backup for essential appliances.
You get a complete off-grid power hub in one compact box. The PowMr POW-LVM4.5K-24V converts your 24VDC battery bank into clean 110VAC power for lights, fridges, and tools. A wide 55V to 350Vdc PV input range lets you wire more panels without worrying about mismatched voltages. The configurable AC-to-battery priority setting means the unit switches smoothly when sunlight fades.
This off-grid inverter bridges solar arrays, battery strings, and household circuits. It reads battery chemistry automatically and adjusts charging steps to match LiFePO4, Lithium, Flooded, Gel, or Lead-acid banks. You keep your existing wiring intact because it accepts nominal 120VAC input while drawing silently from the grid or generator.
You save money by storing cheap nighttime grid power or weekend generator runtime for peak daytime use. The smart battery charger extends cycle life by applying precise float stages. Touch-capacitive buttons resist dust buildup in workshops or barns. Overload and overheating safeguards cut output instantly before components stress.
The unit ships with native RS232/RS485 ports for system integration. Optional WiFi monitoring lets you check state-of-charge from your bed. An anti-dust kit seals ventilation slots for dusty farm environments. Auto-restart resumes operation the moment solar voltage returns. Cold restart forces quick engagement during sudden blackouts. Factory defaults reset with a single switch press.
Model POW-LVM4-24V delivers 4KW continuous capacity. Efficiency stays above 95 percent under full load. Operating temperature ranges from 0°C to 55°C. Storage tolerates down to -15°C. Maximum PV array input reaches 5600W. Weight measures 8.5kg. Physical footprint sits at 400x250x89mm. CE certification confirms EU LVD compliance.
The purchase arrives with the main inverter chassis, mounting hardware, terminal screws, and a quick-start guide. All necessary connection points are pre-labeled for straightforward installation.
Connect your 24VDC battery bank to the heavy-gauge terminals first. Attach solar panels to the labeled PV input leads. Wire your home circuits to the AC output block. Tap the LCd menu to select battery type and set AC or PV input priority. Watch the live readings adjust as sunlight builds.
You gain quiet, maintenance-free energy independence. The integrated BMS communication prevents deep discharge damage. Clear LCD prompts remove guesswork during setup. Reliable switching keeps medical devices and water pumps running through brief grid dips.
Deploy it in cabins without main service connections. Mount it beside wind turbines for hybrid setups. Pair it with generator sets for extended camping trips. Run well pumps, shop vacuums, and lighting grids in remote work sites.
Homeowners seeking reliable blackout protection. RV travelers who want steady AC outlets away from hookups. Farmers protecting irrigation systems from utility failures. DIY builders upgrading basic DC setups to modern AC ecosystems.
Does this inverter charge my batteries automatically?
Yes. The built-in 140A MPPT charger monitors PV input and applies the correct 3-stage algorithm for your chosen battery chemistry.
Can I monitor performance remotely?
Absolutely. Optional WiFi modules connect to the RS485 port so you can view logs and change settings from a phone.
What happens during a sudden power cut?
Cold restart activates the output immediately. The unit switches to battery mode within milliseconds to keep connected loads alive.
Is the display safe in dusty rooms?
The sealed glass top resists particulate intrusion. Touch controls register through light debris without requiring constant wiping.
Will warranty paperwork arrive with the unit?
Standard CE certification documents and a quick-start manual are included in the box for immediate reference.
