All-in-One ESS
Battery storage, power conversion, and energy management in one system — built for home backup, solar storage, and business energy use.
What Is an All-in-One ESS?
An All-in-One ESS is a complete energy storage system that puts the battery, inverter or PCS, battery management, and system control into one cabinet or compact unit. That means less matching work than buying a separate battery, inverter, controller, and cables. On this page you can compare models by capacity, load support, components, installation method, and solar or grid compatibility. Before you choose, check rated power, battery size, backup need, PV input range, grid phase, and whether the package includes the parts your project requires.

Applications
Home Backup
Use a 10.24kWh / 5kW system when the home backup load stays within the 5000W off-grid output rating.
Solar Storage
Choose this setup when the project needs battery storage, inverter output, and PV input in one cabinet. For GSL-AIO-5K10 and GSL-AIO-5K20, the MPPT operating voltage range is 80–550V.
Small Business Backup
Use a 20.48kWh / 5kW system for shops, offices and small business loads within the 5000W off-grid output rating.
Commercial Energy Storage
Use a 215kWh / 100kW C&I cabinet for factory backup, peak shaving and commercial solar storage projects.

FAQ
Does an All-in-One ESS include the inverter?
Many models do. RS-A10 combines controller, inverter, and battery. GSL-AIO-5K10 and GSL-AIO-5K20 include 5000W off-grid output. SolaX ESS-TRENE integrates BMS, EMS, and PCS.
Is an All-in-One ESS the same as a battery?
No. A battery only stores energy. An All-in-One ESS can also include the inverter or PCS, battery management, energy management, solar input, and monitoring.
Can I use it with solar panels?
Yes, when the PV array matches the system PV input limits. RS-A10 uses a 90–230VDC MPPT range. GSL-AIO-5K10 and GSL-AIO-5K20 use an 80–550V MPPT range.
Does adding more battery capacity increase load support?
No. GSL-AIO-5K10 and GSL-AIO-5K20 grow from 10.24kWh to 20.48kWh, but both keep the same 5000W off-grid output rating.
How should I check backup time?
Use the datasheet backup time if listed. If it is not listed, use theoretical full-load runtime only as a sizing reference: battery capacity ÷ rated output power.
