SPE hybrid inverter for low-voltage batteries, 3.5–15 kW
Country: China · Model: SPE
The SPE hybrid inverter for 48 V low-voltage batteries is produced in single-phase versions of 3.5–12 kW and a three-phase version of 15 kVA. It is used for off-grid and backup systems where the battery, panels and the grid or a generator work together.

Description
The battery input accepts 40–60 V, so lithium, lead-acid and GEL batteries are all suitable for the inverter. Single-phase models work with strings of up to 550 V, and the three-phase 15KTL3 accepts up to 1000 V, which simplifies panel layout on a large roof. UPS mode moves the load to the battery as soon as the grid disappears, and the generator input provides a second backup channel for long outages. The peak shaving function cuts consumption peaks using energy from the battery when the supply capacity is limited by the connection conditions. Up to 6–9 units with a total power of up to 90 kW are installed in parallel, and the system is expanded as the load grows.
How to choose
For a single-phase supply the model is chosen by peak load within 3.5–12 kW, and a three-phase supply needs the 15KTL3 of 15 kVA. If the house already has a lead-acid bank, the SPE will work with it, and the inverter will not need replacing when switching to LiFePO4. When the battery is high-voltage or up to 50 kW is needed in one enclosure, the WIT of 29.9–50 kW is better. For a purely off-grid site with motors, consider the SPF T with a low-frequency transformer.

FAQ
Which batteries can be connected to the SPE inverter?
The inverter works with 48 V batteries in the range of 40–60 V, that is, with lithium, lead-acid and GEL batteries.
Is there a three-phase version of the SPE inverter?
Yes, the 15KTL3 model is three-phase, 15 kVA, with a PV input of up to 1000 V.
What does the peak shaving function in the SPE do?
The inverter supplements the grid with battery energy at moments of peak consumption so as not to exceed the permitted supply capacity.
How many SPE inverters can be connected in parallel?
Up to 6–9 units depending on the version, and the total power of such a system reaches 90 kW.
Does the SPE work as a UPS during a power outage?
Yes, the inverter has a UPS mode, so the load moves to the battery when the grid disappears. For long outages a generator is connected to it.
