X1/X3-IES — all-in-one home energy storage systems
Country: China · Model: X1-IES / X3-IES
The all-in-one home system X1/X3-IES combines a hybrid inverter and expandable LFP batteries in one column. The single-phase version has 2.5–8 kVA and up to 40 kWh, the three-phase version 4–15 kVA and 10–60 kWh; both are intended for private houses.

Description
Battery modules are stacked on top of one another under the inverter unit, so capacity is increased without replacing the inverter. The three-phase line has three versions: the X3-IES at 4–15 kVA, the X3-IES-A at 5–15 kW and the X3-IES-P at 4–15 kW. Efficiency is stated at 98–98.6%, and when the grid is lost, switchover to backup takes less than 10 ms. The IP66 housing can be installed outdoors next to a house wall. For cold climates there is the IES-A version with battery heating designed for temperatures down to −30 °C, so it is placed in an unheated garage or on a facade. AFCI protects against arc faults in the solar panel circuits. LFP chemistry is less prone to thermal runaway, which matters when installing in a residential building.
How to choose
First the number of phases at the supply is determined, then the required capacity. A single-phase house with a load up to 8 kVA is covered by the X1-IES, for three phases the X3-IES is taken, and with freezing winters and outdoor mounting the version with heating, the IES-A, is better. If 3–12 kWh is enough, a simpler alternative is the X-ESS G4 with 97% efficiency. For business, where 100 kWh or more is needed, look at ESS-AELIO cabinets of 100–261 kWh.

FAQ
What maximum capacity can be reached in the X3-IES?
The three-phase system scales from 10 to 60 kWh, and the single-phase X1-IES up to 40 kWh.
Can the IES system be installed outdoors in winter?
The housing is rated IP66. For frost the IES-A version is taken, in which battery heating is designed for temperatures down to −30 °C.
What is the efficiency of the X1/X3-IES?
The stated efficiency is 98–98.6% depending on the model.
How fast does the IES switch to backup power?
The switchover time is under 10 ms, so refrigerators, boilers and routers keep working without restarting.
How do the X3-IES-A and X3-IES-P differ?
The X3-IES-A has ratings of 5–15 kW and battery heating for frost, while the X3-IES-P covers 4–15 kW.
