Product introduction:
The 4kW Off Grid Inverter is a high-efficiency hybrid power solution designed for off-grid and backup power applications. Combining solar PV input, battery storage, and grid/generator compatibility, it delivers pure sine wave output with seamless switching between power sources. SiC-based MPPT enables 2x PV oversizing. IP66 survives sandstorms/monsoons. Smart cooling sustains full load at 45℃. Built for off-grid and microgrid scenar.
Product Feature
Configurable input voltage ranges for home appliances and personal computers via LCD control panel.
Smart battery charger design for optimized battery performance.
All-round protection with complete short circuit protection, overload protection, over current protection, over under voltage protection, over temperature protection, etc.
Supports three different voltage levels of 220\230\240Vac.
Combined with solar energy, AC power and battery power, it provides users with an uninterruptible power supply experience.
LCD large screen dynamic flow diagram design, easy to understand the system data and operation status.
Multi-source integration (grid/PV/generator) with 90-280V wide voltage tolerance, ideal for unstable grids.
Modular three-phase expansionr via incremental capacity upgrades.
Easy to use
Remote O&M via WiFi/CAN interfaces enables real-time fault diagnostics and optimization strategies.
Communication
The inverter supports to be set up locally via WiFi, it can be connected to the cloud via WiFi to monitor the operating status of the inverter and the operation of the power plant.
● WiFi (optional): support 2.4G band, need to set the router to 2.4G.
● WiFi signal strength is supported to be viewed via AlpsCloud APP. When the signal strength is less than -60dBm, it is recommended to move the router closer to the equipment or move away from the signal blocker to improve the signal strength.
● Support dry contact communication.
● Support RS232 contact communication for host computer.
● BMS communication supports CAN/RS485 communication.

FAQ
What battery types are compatible?
Our inverter is highly flexible and supports both Lithium-ion and Lead-acid batteries. This allows you to choose the best battery technology based on your budget and performance requirements.
Can the system operate without a battery?
Yes. The inverter supports a battery-less operation mode, directly powering loads from PV or the grid. However, for backup power functionality during a grid outage, a battery is required.
Is the system expandable for future energy needs?
Absolutely. A key feature is its modular scalability. You can start with a single 4kW unit and expand by connecting up to 6 units in parallel to form a larger single-phase system or 9 units for a three-phase system, allowing for incremental capacity upgrades.
What certifications and safety standards does it comply with?
he product is designed and tested in accordance with international safety and EMC standards, including IEC/EN 62109 for safety. It meets the EU directives for CE marking (EMC 2014/30/EU and LVD 2014/35/EU), facilitating its market entry in relevant regions.
The 4kW Off Grid Inverter ensures reliable energy independence with its industrial-grade design (IP66, -40°C~+60°C operation). Its LCD+APP monitoring simplifies system management for end-users.
