- The ET LV Series offers up to 200% PV over sizing and sub 4 millisecond backup switching.
- The BAT14 battery is scalable from 14 kWh to 430 kWh with rapid charge and discharge capability.
GoodWe has introduced a new residential storage solution combining its ET LV Series three phase hybrid inverters with the BAT14 low voltage battery, targeting households across Africa. The integrated system is engineered to deliver high power output, flexible system compatibility and strong backup capability, enabling homeowners to maximise solar self-consumption while ensuring energy security.
The ET LV Series is available in capacities from 5 kW to 20 kW, with the 5 kW model expected in October this year. Designed to accommodate complex rooftop layouts and shading conditions, the inverter incorporates up to four MPPTs and supports an input current of 20 A per string. With 200% PV oversizing capability, the system enables increased solar harvesting and improved self-consumption rates.
The 15 kW and 20 kW models feature dual independent battery inputs rated at 416 A, allowing faster charging, expanded storage capacity and greater installation flexibility. The inverter delivers seamless transition to backup mode in under 4 milliseconds, ensuring continuity of supply during grid outages and protecting sensitive household appliances.
With 150% unbalanced output capability, the ET LV Series maintains stable performance in multi-phase environments with uneven load distribution. It also supports micro grid functionality, enabling operation alongside PV inverters to create a self-sustaining local grid. This makes it suitable for weak grid and off grid applications, particularly relevant in many African markets.
The BAT14 battery offers a nominal capacity of 14.3 kWh and can be scaled in parallel up to 30 units, allowing expansion from 14 kWh to 430 kWh. This modular approach enables homeowners to start with a smaller system and expand capacity as energy demand grows, including the addition of new appliances or EV charging.
The battery delivers 0.8 C charging and 0.94 C continuous discharging rates, providing rapid response to load fluctuations while maintaining battery health. Equipped with 280 Ah cells and integrated heating technology, the BAT14 is designed to operate in temperatures as low as minus 20 degrees Celsius, ensuring reliability across diverse climate conditions.
Safety features include AI powered AFCI 3.0 technology that continuously monitors circuits to detect and mitigate arc faults, reducing fire risk. Type II surge protection is integrated on both AC and DC sides to safeguard the system against voltage spikes caused by lightning or grid instability.
The BAT14 battery is compatible with the ET LV three phase hybrid inverter as well as GoodWe’s ES Uniq single phase series from 3 kW to 12 kW. The ET LV inverter also integrates with the Lynx A G3 and Lynx U G3 low voltage batteries, providing installers with flexible configuration options to suit different budgets and project requirements.
The solution includes intelligent energy management functionality with optimised charge and discharge strategies and peak valley tariff management to reduce electricity costs and maximise solar utilisation. Users benefit from 24/7 remote monitoring of generation, storage status and consumption patterns, ensuring full system visibility and control.
By combining high PV input capacity, rapid backup switching and scalable storage, GoodWe positions its latest residential solution as a resilient and future ready offering for households seeking greater energy independence and cost savings across Africa.
