EPEVER HP3522-AH1250P20A — Hybrid Inverter/Charger

In environments with irregular power supply or the need to efficiently utilize solar energy, the EPEVER HP3522-AH1250P20A provides a reliable solution for managing hybrid systems. This inverter/charger combines pure sine wave to protect sensitive electronics, MPPT technology to maximize the use of solar input up to 4000W, and 93% conversion efficiency, which increases overall energy efficiency. With its flexibility to support both battery and battery-free operation and the ability to parallel up to 12 units, it is ideal for residential and commercial applications requiring stable and cost-effective power.

Efficient energy management and charging

The device allows charging from multiple sources, including the grid, diesel generators and solar panels, with the ability to adjust the maximum charging current up to 120 A, ensuring fast battery charging while maintaining grid protection. With MPPT voltage range 85-400 V DC, it maximizes gains from photovoltaic panels even under changing lighting conditions. PFC technology optimizes power factor, which minimizes grid capacity requirements and reduces operating costs.

Advanced protection and reliability

The inverter is equipped with extensive protection functions, including overvoltage, undervoltage, overload, short circuit and overheating protection, which ensures long-term reliability and protection of connected devices. The pure sine wave output protects sensitive electronics, while 10 ms switching time between the inverter and the grid ensures minimal power outages. The high peak capacity of 7000 W allows you to cover short-term high power demands.

Scalability and system flexibility

The device supports parallel connection of up to 12 units (expandable to 16), allowing for power scaling for more demanding applications. Both single-phase and three-phase operation can be configured, making it ideal for larger systems or industrial applications. The integrated RS-485 port and optional modules (Wi-Fi, 4G, TCP) ensure easy remote monitoring and system management.
