Haier H1PL-1J5K-EU5kW single-phase low-voltage hybrid inverter, 2 MPPT

Overview

The H1PL-1J5K-EU is a 5kW single-phase hybrid inverter for 48V batteries, with 105A charge and discharge current and a recommended PV array of up to 8kW on two MPP trackers. Backup output switches in under 10ms and reaches 7kVA for 60 seconds. The 5kW model supports parallel operation with identical units sharing one battery, and generator connection, and reaches more than 97.5% maximum efficiency.

• 3, 3.6, 5 and 6kW single-phase, 220/230V
• 48V battery (42–58V), lithium or lead-acid
• 2 MPPT, 600V max. PV input, AFCI built in
• Backup switch-over under 10ms
• Up to 60s backup overload (e.g. 8kVA on the 6kW)
• IP66, natural cooling, operation up to 4000m

How it works

The H1PL-1J is a single-phase hybrid inverter that works with a low-voltage battery between 42V and 58V, either lithium-ion with CAN or RS485 BMS link or lead-acid, from 50Ah to 2000Ah. The battery stage is galvanically isolated by a high-frequency transformer, while the PV side has two MPP trackers rated 16A with a 90–520V range and a 600V maximum. Haier recommends PV arrays up to 1.6 times the AC rating, for example 9.6kW on the 6kW model.

Charge and discharge power equals the rated output, from 3kW at 62.5A to 6kW at 125A. An Eastron SDM120CTM meter with CT is supplied for self-consumption and export control. In the E-Tower LV system Haier pairs these inverters with its B051100P03-H 5.12kWh LFP modules.

Operating modes and backup

Four work modes are available: self-use (default), feed-in priority, peak shaving with a configurable grid import limit, and pure off-grid operation. Time-of-use windows control when the battery charges or discharges. The backup port takes over within 10ms and can deliver 1.4 times rated apparent power for 60 seconds on the 3kW model and about 1.33 times on the 6kW model. It must never be connected to the grid.

Installation and compatibility

The IP66 housing measures 405×480×205mm and weighs 24.2kg; cooling is natural convection and noise stays below 35dB. The manual asks for at least 400mm between inverters or other objects and 800mm from the bottom of the unit to the floor, away from direct sunlight. PV inputs use MC4 connectors and AC quick-connect plugs.

Only the 4.6, 5 and 6kW models can run in parallel, with identical units sharing one battery; three units can also be connected across the three phases of the grid, but the backup ports cannot be paralleled as a three-phase supply. Generator support is limited to the 5 and 6kW models. Grid codes in the manual include CEI 0-21, VDE-AR-N 4105, EN 50549-1, C10/11, G98 and G99.

Monitoring and settings

Commissioning is done through the app over Bluetooth, using the supplied antenna; a Wi-Fi/LAN stick datalogger connects the inverter to the cloud. Five LEDs show battery, power, Wi-Fi, Ethernet and Bluetooth status. Battery model, meter type and position, over-discharge and force-charge SOC and the grid code are set in the app.
