Wall Mounted Solar Power Station | LiFePO4 All-in-One Solar Energy Storage System
The KINPOWER Model B wall mounted solar power station combines a LiFePO4 battery and a bidirectional inverter in one compact unit, so you get stored solar energy and AC output without a separate inverter. Available in three sizes — 2kWh/1000W, 3kWh/1500W and 4kWh/2000W — this all-in-one solar energy storage system is designed for home backup, off-grid cabins, RVs and travel. It outputs pure sine wave AC at 220–230V, 50Hz, which can power everyday appliances such as refrigerators, lights, cooling fans, laptops, cameras, electric ovens and power tools.
Why Choose the KINPOWER Model B Wall Mounted Solar Power Station
Built-in bidirectional inverter. The inverter is integrated into the battery unit, so the system charges from solar or the grid and discharges AC power to your loads — no separate inverter purchase or wiring setup is required.
LiFePO4 chemistry with a long service life. The battery uses lithium iron phosphate cells rated for at least 10,000 cycles, delivering stable, cost-effective performance for daily charging and discharging.
Pure sine wave AC output. The 1000W, 1500W and 2000W models provide clean, stable AC output at 220–230V, 50Hz, suitable for sensitive electronics and standard household appliances.
Dual charging and fast backup switching. You can charge the battery from solar panels or from AC grid/generator input, and the EPS (UPS) function switches to battery power in under 50ms during a grid outage.
Easy monitoring and flexible output. An LCD display, AC/DC status lights and a USB 5V 2A port make the unit simple to operate, while the metal enclosure and wall-mounted design keep it tidy and durable.
Model Overview and Specifications
Three models cover everyday needs from 2kWh to 4kWh of storage and 1000W to 2000W of continuous AC output, so you can match the system to your household load and solar setup. All models use LiFePO4 chemistry with a cell life of at least 10,000 cycles, support both solar and AC charging, and share the same operating temperature range of −10 to 40°C, storage temperature of −15 to 60°C, and a working noise level below 50dB.

H2：How the All-in-One Solar Energy Storage System Works
During the day, solar panels charge the built-in LiFePO4 battery through the PV input. When the sun goes down, or when electricity rates are highest, the inverter converts the stored energy into pure sine wave AC to power your home. If the grid fails, the EPS function switches to battery power in under 50ms so essential appliances keep running without interruption.
H2：Common Applications
Installation and Operation
The unit is wall mounted and ready to use: connect solar panels or AC input, press and hold the AC or DC button for two seconds to start output, and read real-time data such as input and output voltage, frequency, battery level and PV power on the LCD display. The display turns off after 25 seconds of inactivity to save energy.
Safety and Protection
The battery is a lithium iron phosphate (LiFePO4) unit inside a metal-sprayed enclosure. Protection covers input and output over/under voltage, overload, overcurrent, short circuit, overtemperature, and battery-side charge, discharge and temperature protections, as documented in the user manual.
