Hoymiles HIS-3L-G3 3 kW Single-Phase Hybrid Inverter with 2 MPPT Channels

The HIS-3L-G3 3 kW from Hoymiles (MPN: HIS-3L-G3) is a single-phase hybrid inverter that combines a PV system, battery storage, and backup power in a single system. The inverter offers a rated AC output power of 3,000 W, two independent MPPT trackers for up to 6,000 W of recommended PV power, and supports lithium and lead-acid batteries with voltages ranging from 40 to 60 V. Various energy management modes, monitoring via the S-Miles Cloud, and a backup output with a 0 ms switchover time round out the range of features.

3 kW hybrid inverter for PV and storage systems

• 3,000 W rated output power
• Up to 6,000 W recommended PV power
• 2 independent MPPT trackers, each with one string input
• For lithium and lead-acid batteries with 40–60 V
• 10 ms switchover time at the backup output
• Up to 6,000 VA for 10 seconds in backup mode
• Multiple energy management modes, including self-consumption, peak shaving, and time-of-use
• Remote monitoring via the S-Miles Cloud
• Passive cooling via natural convection
• Up to 10 inverters can be operated in parallel

Flexible control of solar energy and battery storage

Various operating modes are available for the demand-based use of solar energy and battery storage. In self-consumption mode, the generated PV energy is primarily used to power connected loads, and any excess energy is then stored in the battery storage system. Other modes include limiting grid draw peaks via peak shaving or time-dependent control of charging and discharging processes via time-of-use pricing.

Backup Power Supply Without Interruption

Via the separate backup output, the HIS-3L-G3 provides a rated power of 3,000 W. For short-term load peaks, up to 6,000 VA is available for 10 seconds. With a switchover time of 0 ms, designated loads can continue to be supplied without any interruption in power, provided the overall system is designed accordingly.

Monitoring and Compact Design

The S-Miles Cloud allows for convenient remote monitoring and analysis of the PV and storage system’s operating data. The inverter is designed for space-saving wall mounting and operates particularly quietly thanks to passive cooling. The robust housing also offers reliable protection against external influences and enables versatile use.

Integrated Protection Functions

The HIS-3L-G3 features several integrated protection mechanisms for PV and grid operation. These include protection against islanding, PV reverse polarity protection, insulation resistance monitoring, ground fault current monitoring, as well as AC overcurrent and short-circuit protection. Additionally, AC overvoltage and undervoltage protection, as well as Type II overvoltage protection on both the DC and AC sides, are provided.
