High-Power Hybrid Solar and Battery Storage

The GEN-LB-EU 8K combines solar generation, low-voltage battery storage, grid connectivity and generator support within a single hybrid inverter. Its 48V battery architecture and 167A charge and discharge capability make it particularly suitable for larger residential battery systems and light commercial installations where higher energy throughput is required.

With up to 8,000W of battery charge and discharge power, the inverter can make effective use of strong solar generation during the day and provide substantial stored energy output when demand increases. High current capability also supports rapid charging during favourable solar conditions or lower-cost grid tariff periods.

12kW Solar PV Input with Dual MPPTs

Up to 12,000W of connected solar PV capacity gives the GEN-LB-EU 8K strong solar harvesting capability relative to its 8kW AC output. Two independent MPPT trackers use a 2:2 configuration, giving installers additional flexibility when working with larger arrays or multiple solar orientations.

The 120-550V MPPT operating range, 600V maximum PV input voltage and 25A maximum current per MPPT allow compatibility with a wide range of modern high-power solar modules and string arrangements. MPPT efficiency of up to 99.9% helps maximise available solar generation throughout changing conditions.

Generator Integration and Energy Management

A dedicated generator port with automatic control makes the GEN-LB-EU 8K particularly useful for installations where backup generation forms part of the overall energy strategy. The inverter can combine solar PV, battery storage, grid power and generator input within a more flexible hybrid energy system.

Time-of-use and weather-based optimisation can help determine when batteries should be charged or discharged, supporting lower grid import costs and improved use of available solar generation. This is particularly useful for UK homes and businesses using variable or off-peak electricity tariffs.

On-Grid, Off-Grid and Scalable Operation

The inverter supports both grid-connected and off-grid operation, allowing it to be used in systems that require normal grid interaction alongside reliable battery-backed power. A 60A continuous AC passthrough rating also supports substantial connected loads within appropriately designed installations.

Up to 10 inverters can operate in parallel, providing a scalable route for larger residential and light commercial solar battery storage systems where greater power capacity may be required over time.
