Sunsynk 5kW Hybrid Compact Inverter overview

The Sunsynk 5kW Hybrid Compact Inverter – SG04LP1-EU-SM2 LV is a next-generation hybrid inverter designed to give users full control over how energy is generated, stored, and consumed. It combines solar charging, battery management, and AC power conversion into a compact, installer-friendly unit.

This inverter is built on a 48V low-voltage platform, making it compatible with most popular lithium and lead-acid battery systems used in South Africa.

Smart hybrid power for South African conditions

With a 5kW continuous output, this inverter is capable of powering essential household and office loads such as lighting, plug circuits, refrigerators, TVs, computers, network equipment, and selected pumps.

The system intelligently blends energy from solar panels, batteries, and the grid to reduce electricity costs while ensuring reliable backup power during outages.

Solar charging and dual MPPT optimisation

The Sunsynk 5kW Hybrid Compact Inverter features dual MPPT trackers, allowing two independent solar strings. This helps optimise solar production when panels are installed on different roof orientations or experience partial shading.

With support for up to approximately 6.5kW of solar PV, the inverter enables strong daytime generation and effective battery charging.

Battery compatibility and fast response

Designed for 48V battery banks (40–60V range), this inverter supports both lithium-ion and lead-acid batteries. Intelligent battery management, including lithium BMS self-adaptation, ensures safe charging, efficient discharging, and long battery life.

High charge and discharge current capability allows the system to respond quickly to changing loads and backup demands.

Compact design and quiet operation

The compact enclosure makes this inverter ideal for installations where wall space is limited. Natural cooling ensures quiet, fan-less operation, reducing noise and maintenance while improving long-term reliability.

The IP65-rated enclosure allows installation in sheltered indoor or outdoor locations.

Flexible operating modes

The Sunsynk 5kW Hybrid Compact Inverter can be configured for multiple system types:

• Backup-only systems using batteries

• Grid-tied solar systems without batteries

• Full hybrid solar-battery systems

• Off-grid operation with generator support

This flexibility allows systems to be expanded over time as energy needs change.

Monitoring, control and protection

Real-time monitoring is available via Wi-Fi and the Sunsynk app or web portal. Users can configure time-of-use schedules, battery charge priorities, and export limits to match their energy strategy.

Built-in electrical protections include overload, short-circuit, and over-temperature protection, as well as advanced battery management features.
