The Senergy SE 3/3.6/5/6KHB-D1/LV-ECO is a 3kW–6kW Single Phase Hybrid Inverter designed for residential solar energy storage, self-consumption and backup power systems. The series includes 3kW, 3.6kW, 5kW and 6kW models, allowing installers and distributors to match the inverter capacity to different household loads and PV system sizes.

The inverter manages electricity from PV modules, a 48V battery, the utility grid and a generator. It supports 40–60V lithium-ion or lead-acid batteries and provides single-phase 220V, 230V or 240V output at 50Hz or 60Hz.

With up to 200% PV oversizing, 9kW usable PV power, two MPPT trackers and 18A input current per MPPT, the series is compatible with modern high-power PV modules. It can also switch to backup mode during an outage, helping maintain electricity for selected household loads.

3kW–6kW Single Phase Hybrid Inverter Specification

Residential Applications of 3kW–6kW Single Phase Hybrid Inverter

• Residential solar self-consumption
• Home battery energy storage
• Backup power during utility outages

How to Select the Right Model

Choosing between the 3kW, 3.6kW, 5kW and 6kW versions should be based on the maximum simultaneous load, PV array capacity, battery capability and required backup duration.

Advantages of 3kW–6kW Single Phase Hybrid Inverter

• Four power ratings: Choose from 3kW, 3.6kW, 5kW and 6kW nominal AC output.
• High PV capacity: Supports up to 12kW PV access power and 9kW usable PV power.
• 200% PV oversizing: Allows a larger PV array to improve energy generation under lower-irradiance conditions.
• Dual MPPT design: Two independent MPPT trackers support arrays installed on different roof orientations.
• High-current module support: Each MPPT accepts up to 18A, with a maximum short-circuit current of 25A.
• Low-voltage battery compatibility: Works with 40–60V lithium-ion or lead-acid batteries.
• High battery current: Maximum charge and discharge current reaches 135A, depending on the selected model.
• Flexible energy-source integration: Supports PV, batteries, the utility grid and generator input.
• Smart-load support: Helps manage different loads according to available energy and system settings.
• AC-coupling capability: Provides flexibility when upgrading or integrating certain existing solar systems.
• Parallel operation: Multiple units can operate together, and three inverters can be configured for a three-phase system.
• Backup power switching: A typical 10ms transfer time helps protect selected loads against grid interruptions.
• 41A grid passthrough: Allows utility power to supply loads through the inverter when required.
• Scheduled energy management: Six configurable charging and discharging periods support time-of-use strategies.
• Remote monitoring: Built-in Wi-Fi supports remote system monitoring and software upgrades.
