The Chinese manufacturer said its new OG02 series includes IP-65 rated inverters with AC output power from 3 kW to 6 kW. The new products also have a maximum efficiency of 97.6% and a European efficiency of 96.5%.
Chinese inverter manufacturer Deye has launched a new series of off-grid inverters
The OG02 series consists of four models with AC output powers ranging from 3.0 kW to 6.0 kW. It’s an evolution of the company’s OG01 line, which was introduced last year.
According to the manufacturer, the OG02 inverters can switch from mains to battery power within 4 ms, providing continuous power to more than 99% of connected loads. The company says this fast switching time helps prevent interruptions, system restarts and unstable motor operation that can occur with conventional off-grid inverters, which typically require 10 ms to 20 ms.
The inverters have PV string input capacities ranging from 6 kW to 12 kW. The maximum operating input current is between 18 A and 36 A depending on the model, while the maximum short circuit current ranges from 27 A to 54 A.
For all models, the MPPT voltage range is 150 V to 425 V, with a nominal input voltage of 370 V.
All models measure 30.6 cm x 42.75 cm x 17.58 cm and weigh 9.3 kg. They are designed to operate in temperatures from –40 C to 60 C, at altitudes up to 3,000 m, and at a noise level of less than 46 dB.
According to the manufacturer, the inverters have a maximum efficiency of 97.6% and a European efficiency of 96.5%. They come with a five-year manufacturer’s warranty.
Deye said the OG02 series supports peak charging and discharging based on electricity rates based on the time of use, allowing users to optimize energy consumption based on fluctuating grid prices. The system prioritizes photovoltaic energy generation, stores excess energy in batteries and discharges during peak tariff periods to reduce electricity costs and improve return on investment.
The company said the series features an IP65 rated enclosure that provides better protection against dust and water compared to conventional IP20 inverters. The products are designed for use in environments with a lot of dust, extreme cold and high temperatures. Deye added that the inverters use an independent cooling air duct that is completely isolated from the electrical system, reducing dust ingress, improving cooling stability and preventing failures due to dust accumulation, thus extending the life of the product.
