Which model is this listing?

This listing is the single SKU SUN-6.6K-OG03LP1-EU-AM2: 6.6 kW rated AC, 140 A charge/discharge, 2× PV oversizing, IP65, 8.6 kg.

Is this a hybrid or off-grid inverter?

OG03LP1 is Deye’s off-grid single-phase series (grid/generator input to battery supported). It is not the three-phase SG01HP3 hybrid platform.

Does it support a diesel generator?

Yes. Generator (and grid) input can charge the battery — on 6.6K, max input power to battery is 6600 W with 35 A generator input current.

How many units can I parallel?

Up to 16 inverters and 32 batteries in parallel. On/off-grid switching is specified at 4 ms.

What warranty is included?

5 years per the datasheet. Confirm terms for the installation country with Deye warranty policy.
