Deye Hybrid vs Off-Grid Inverter: SUN-5K-SG04LP1-EU vs SUN-5K-OG01LP1-EU-AM2
Both of these Deye inverters are single-phase, both have a rated AC output power of 5000 W and both work with a battery in a 40–60 V battery voltage range. The SUN-5K-SG04LP1-EU is a hybrid inverter; the SUN-5K-OG01LP1-EU-AM2 is an off-grid inverter. The ratings match, so the choice is about what each record says the unit does beside a grid connection, how much PV current it accepts and what it weighs. This page compares the two product records row by row. Where a row exists on one record and not on the other, we say so rather than fill the gap.

What one record lists and the other does not
The SUN-5K-SG04LP1-EU record lists anti-islanding protection, AC coupling support, residual current detection, an AC voltage tolerance, a power factor range and six charge/discharge time periods. The SUN-5K-OG01LP1-EU-AM2 record lists none of those rows; it lists instead a pure sine wave output and a generator input current of 35 A. Both records list diesel generator support and a maximum continuous AC pass-through current, which is 40 A on the SUN-5K-SG04LP1-EU and 35 A on the SUN-5K-OG01LP1-EU-AM2. Those rows, more than the word in the name, are the difference between the two types.
AC output: the same 5000 W
The SUN-5K-SG04LP1-EU has a rated AC output active power of 5000 W and a maximum apparent power of 5500 VA, at 220/230 V. The SUN-5K-OG01LP1-EU-AM2 has a rated AC output active power of 5000 W and a maximum apparent power of 5000 VA, at 230 V. Both records state a peak power of twice the rating for 10 seconds. The SUN-5K-SG04LP1-EU and the SUN-5K-OG01LP1-EU-AM2 also share a maximum efficiency of 97.6 % and a European efficiency of 96.5 %.
Solar input: same power, more current off-grid
Both inverters have 2 MPPTs with one string each, a maximum PV input power of 8000 W, a maximum PV access power of 10000 W, a 500 V maximum PV input, an MPPT range of 150–425 V and a 125 V start-up voltage. The current is where they differ: the maximum operating PV input current is 13+13 A on the SUN-5K-SG04LP1-EU and 18+18 A on the SUN-5K-OG01LP1-EU-AM2. The SUN-5K-OG01LP1-EU-AM2 record lists an arc fault circuit interrupter as fitted; on the SUN-5K-SG04LP1-EU it is optional.
Battery, cabinet and site limits
Both work with a lead-acid or lithium-ion battery; the SUN-5K-SG04LP1-EU and the SUN-5K-OG01LP1-EU-AM2 each have a maximum charge current of 120 A and a maximum discharge current of 120 A, and both allow 16 units in parallel. The SUN-5K-SG04LP1-EU measures 330 × 433 × 228 mm and weighs 17 kg, with natural cooling, a noise level below 30 dB and a maximum altitude of 2000 m. The SUN-5K-OG01LP1-EU-AM2 measures 306 × 427.5 × 175.77 mm and weighs 12.2 kg, with intelligent air cooling, a noise level below 55 dB and a maximum altitude of 3000 m. Both are IP65, operate from -40 to 60 °C and carry a 10-year warranty.
Which one for which load
Choose the SUN-5K-SG04LP1-EU for a home or business with a utility connection where the inverter works beside the grid: its record carries the grid-side protections and the time periods for charging and discharging, and its natural cooling suits a wall near living space. Choose the SUN-5K-OG01LP1-EU-AM2 for a site that runs on solar, a battery and a generator: it is lighter, accepts more current from each string and lists a generator input. The loads themselves do not separate them — the rated output is the same.

Conclusion
At the same rated output power of 5000 W, the two records describe two different jobs. The SUN-5K-SG04LP1-EU carries the grid-side rows — anti-islanding protection, AC coupling, six charge and discharge periods — in a quiet, naturally cooled 17 kg cabinet. The SUN-5K-OG01LP1-EU-AM2 is the lighter unit at 12.2 kg, takes more PV current per MPPT and has an arc fault circuit interrupter fitted. Decide by whether a grid connection is part of the system.
