What are the HP-AHP65A highlights?

① IP65 high protection rating, suitable for harsh outdoor environments

The IP (Ingress Protection) rating system is an international standard used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt, etc.) and moisture. The rating system is defined by international standard IEC 60529.

The first digit indicates the level of protection that the enclosure provides against access to hazardous parts and the ingress of solid foreign objects. A rating of “6” means that the enclosure is dust-tight and complete protection against contact (a dust-tight product). The second digit indicates the level of protection that the enclosure provides against harmful ingress of water. A rating of “5” means that the enclosure can withstand water projected by a nozzle against the enclosure from any direction shall have no harmful effects.

IP65 rating on a product means that it is protected against dust ingress to the point where it will not interfere with the operation of the equipment; it is also protected against low-pressure jets of water from all directions

Product details

l Supports two operating modes：Battery mode ＆ None-Battery mode

 

The HP-AHP65A system offers versatile power management solutions tailored to different energy generation and storage needs.

In the non-battery mode, the system directly connects to a PV array, utilizing an MPPT Charger to optimize solar power conversion. Even without batteries, it efficiently channels solar energy to household appliances and AC loads, ensuring an uninterrupted power supply.

Alternatively, during low sunlight or at night, the system seamlessly switches to draw power from the utility grid or an external generator. This ensures continuous power flow to connected loads, enhancing reliability.

For users requiring energy storage, the second operating mode incorporates a battery configuration. The HP-AHP65 inverter/charger intelligently manages energy, charging batteries during surplus power from the PV array or utility grid, and discharging stored energy when needed.

Both setups offer interactive monitoring through the LCD panel, allowing users to easily track system performance and status. These connection options demonstrate the adaptability and robustness of the HP-AHP65 system, providing users with a reliable power management solution for diverse scenarios.

l 4 Charging Modes

PV charge only: In this mode, the battery is charged solely from the solar panels without relying on an external power source. It is suitable for areas without access to the grid and where solar energy is abundant.

PV (solar) Priority: This mode prioritizes solar power, allowing the system to maximize the utilization of solar energy and reduce dependence on the grid. This helps lower energy costs, especially in areas with ample sunlight, significantly reducing electricity expenses.

PV+ Utility Charge: This mode provides a more stable power supply. Solar panels take precedence in supplying power, and when solar energy is insufficient or during nighttime, the system switches to grid power. This ensures a continuous and stable power supply even when solar panels are unable to operate or sunlight is limited.

Utility Priority: In this mode, the system primarily relies on grid power and only switches to alternative energy sources when grid power is unavailable or unstable. This mode is suitable for scenarios that rely on grid power and prioritize power supply stability.
