SunEnergyXT 500 – Smart 5 kWh Solar Storage with 800 W Feed-in Power and 2,400 W Backup Power
The SunEnergyXT 500 is a powerful all-in-one electricity storage system for balcony power plants and photovoltaic systems. With a usable storage capacity of 5 kWh, four independent MPPT inputs and an integrated UPS function, the system combines solar storage, inverter and energy management in one compact device.
The basic version feeds up to 800 W into the household grid, making it ideal for balcony power plants according to current regulations. At the same time, a powerful 2,400 W backup socket is available in emergency power mode, so that important consumers can be reliably supplied even in the event of a power outage.
Thanks to its modular design, the system can be expanded at any time. Up to three main units and additional battery storage units can be combined to create a powerful energy system for growing demands.
The four integrated MPPT trackers each support up to 625 W of PV power and allow the connection of different module fields. With a maximum PV charging capacity of 2,400 W, automatic battery heating for winter operation and IP65 protection class, the storage unit is suitable for both indoor and protected outdoor use.
With the SunEnergyXT app, you can always keep track of solar yield, battery status, household consumption and grid feed-in. In addition, the system supports local control without a cloud, Home Assistant and smart meters from Shelly, EcoTracker and bitShake.
