Description
xThe Deye SUN-5K-SG04LP1-EU-SM2 is a 5kW single-phase hybrid inverter for 48V low-voltage battery systems, built for residential backup and self-consumption.
It takes up to 8kW of PV across two independent MPP trackers and charges and discharges a 48V battery bank at up to 120A. Grid, PV, battery and generator are all managed by the one unit, with six programmable time periods for charging and discharging. Rated IP65 and naturally cooled, it mounts indoors or in a sheltered outdoor position without an enclosure.
Why installers pick this unit
- Two MPP trackers (18+18A) for arrays across two roof faces
- 120A battery charge and discharge, self-adapting to the battery BMS
- Parallels up to 16 units on- and off-grid, with multiple battery banks
- AC coupling to retrofit an existing grid-tied PV array, plus generator support
- 97.6% peak efficiency (96.5% Euro), fanless natural cooling, WiFi/RS485/CAN comms; NRS 097 is among the listed grid codes
Good to know before you quote it
- Low-voltage (40-60V) batteries only.
- Single-phase. For three-phase sites use the Deye 3-phase range.
- This is the SG04LP1 SM2 revision — confirm firmware/BMS compatibility with the battery brand.
- Warranty is 5 or 10 years depending on the final installation site — confirm against Deye's warranty policy for the address.
