The SolaX X1-AC 3.0kW AC battery inverter and 5.8-17.3kWh SolaX T58 5.8kWh battery energy storage system with capacity from from 5.8kWh to 17.3kWh (5.8-17.3kWh/3.0kW AC coupled ESS) includes:
- 1x SolaX T58 Triple Power HV 5.8kWh LFP Battery System including
- SolaX Triple Power HV 5.8kWh LFP Main Battery MASTER V2, and
- 1x or 2x SolaX Triple Power HV 5.8kWh LFP Main Battery SLAVE V2,
- 1x SolaX X1-AC 3.6kW AC Coupled Battery Inverter.
This 5.8-17.3kWh/3.6kW AC coupled ESS efficiently manages energy usage, ensuring a stable electricity supply while reducing costs by charging the battery with solar power or low-cost off-peak Octopus electricity. Coupled with an on-grid solar power source, it provides continuous 24/7 electricity for your home.
The 3.6kW X1-AC AC coupled inverter is designed to be compatible with an external backup generator, providing seamless electricity supply during extended grid outages when the battery storage is depleted.

SolaX 5.8kWh triple power T58 master and slave battery module:
A high-performance, scalable battery storage module with a modular design for maximum flexibility. It features easy installation, plug-and-play functionality, 95% charge/discharge efficiency, 100% depth of discharge, and a cycle life exceeding 6,000 cycles.
- SolaX X1-AC 3.6kW AC coupled battery inverter: A high-quality inverter that converts solar energy to AC power, compatible with high-voltage batteries. Suitable for both indoor and outdoor installation, it features natural cooling, quiet operation, and low maintenance.
-
SolaX X1-AC 3.6kW AC battery inverter operating modes:
- Self-use (default): Without PV input, the battery discharges to power local loads first. If battery capacity is insufficient, the grid supplies power.
- Feed-in priority: In this mode, the inverter prioritises feeding power to the grid, then supplies local loads, and finally charges the battery. This is ideal in areas with high feed-in tariffs.
- Forced time use: Charging and discharging times can be set flexibly in this mode.
-
Backup mode: The battery reserves capacity while the grid is on. In the event of a grid outage, the battery discharges to keep emergency loads functioning normally, especially useful in areas prone to blackouts.
The system seamlessly integrates with smart Octopus tariffs, allowing for automatic optimisation with Plunge Prices and super-low tariffs. With solar panels and this battery storage system, you can significantly reduce your electricity costs.
