Introduction:

The POW-HVM4.5K-24V-E is a 4.5KVA 4200W/4.2KW 24V hybrid solar inverter—an all-in-one unit combining PV inversion, charging, and energy storage capabilities—designed specifically for residential and small-office energy storage systems. It integrates four core modules: solar charging, grid charging, inverter output, and lithium battery BMS communication management. Eliminating the need for separate controllers or chargers, this single unit enables the construction of a complete PV energy storage power system. It is compatible with both lead-acid batteries and lithium batteries (supporting RS485 communication protocols) and operates in dual on-grid/off-grid modes. It supports solar self-consumption, independent off-grid power supply during outages, and grid-tied operation for supplementary charging. This unit serves as the core power solution for overseas residential energy storage, RVs, small businesses, and outdoor off-grid projects.

Advantage:

1. All-in-One Integrated Design: Combines an inverter, solar MPPT controller, and grid charger into a single unit, reducing wiring and installation costs;

2. Dual Battery Compatibility: Compatible with standard 24V lead-acid batteries and 24V lithium batteries (supporting RS485 communication protocols) with intelligent BMS integration for protection;

3. Grid-Tie/Off-Grid Dual Mode: A single system handles daily grid-tied energy savings and emergency off-grid power during outages, meeting mainstream residential needs in the US;

4. Pure Sine Wave Output: Harmonic-free power that is safe for refrigerators, air conditioners, and sensitive home appliances;

5. Fully Customizable Parameters: Manual settings available for charging voltage, low-voltage protection, equalization cycles, grid charging current, and grid voltage range;

6. Intelligent Low-Load Standby: Automatically enters sleep mode during very low loads to minimize no-load power consumption;

7. Large Visual LCD Screen: Displays all operating parameters at a glance; fault codes enable quick troubleshooting;

8. Comprehensive Safety Protections: Includes safeguards against over-voltage, under-voltage, overload, over-temperature, fan failure, and battery reverse polarity;

9. Easy Installation: Features standard-torque terminals (2–3 Nm for battery cables) and a universal RJ45 communication port for simple wiring.
