Deye On-Grid inverters
Deye on-grid inverters for commercial and industrial PV systems. Power 10–50 kW.
Buying guide
Deye grid-tied (on-grid) inverters convert energy from the panels directly into alternating current for use in the building and feed the surplus into the grid. They do not use a battery, which makes them a simpler and cheaper solution where most of the energy is consumed during the day. The range includes a single-phase 10 kW model and three-phase 20, 30 and 50 kW models.
When to choose on-grid instead of a hybrid
An on-grid inverter pays off mainly for businesses, warehouses, workshops and agricultural sites where consumption takes place mostly during the day. If you need to store energy for the evening or have backup during a grid outage, choose a hybrid inverter with a battery.
On larger roofs, several on-grid inverters are often combined, or an on-grid inverter is combined with a hybrid inverter when the system is expanded in stages.
Model overview
The SUN-10K-G is single-phase, has two MPPT trackers and efficiency of up to 97.7%. The SUN-20K-G05 has two MPPT trackers and efficiency of up to 98.5%. The SUN-30K-G04 has two MPPT trackers with three strings each, the SUN-50K-G04 four; efficiency of up to 98.6% and 98.7% respectively — they are intended for larger commercial and industrial PV plants.
The 10 kW model is single-phase (230 V), the 20–50 kW models are three-phase; all have WiFi monitoring and a 10-year warranty. The lightweight design — from 15.3 kg for 10 kW to 37.1 kg for 50 kW — simplifies installation.
Frequently asked questions
Can I add a battery to an on-grid inverter later?
An on-grid inverter does not support a battery. If you plan to store energy, choose a hybrid inverter, or add a hybrid inverter with a battery to the existing on-grid system.
How many MPPT trackers do Deye on-grid inverters have?
The SUN-10K-G, SUN-20K-G05 and SUN-30K-G04 have two MPPT trackers, the SUN-50K-G04 four.
