The Deye SUN-20K-SG05LP3-EU-SM2 is a three-phase low-voltage hybrid inverter aimed at larger villas, farm facilities and small C&I sites. It keeps the installation on a 48V battery platform while providing three-phase AC output for balanced distribution across site loads.
Project advantages:
100% unbalanced output helps handle real operating conditions where loads are uneven across phases.
AC-coupling support makes it suitable for storage upgrades on existing PV installations.
Generator charging and time-of-use control help sites manage backup energy and electricity costs.
Parallel operation gives distributors a scalable product family instead of a one-off inverter size.
At 20kW, this model suits customers who need more than simple grid-tie generation: battery integration, backup operation and load flexibility are the main reasons to specify it.
