250 kW/650 kWh

Qiqian, the forgotten paradise on earth. It is a quiet village in the deep birch forest of the Greater Khingan Mountains, northeast China.

There is a troop of firefighters protecting residents from forest fire. However, the extremely cold weather and unplugged lifestyle makes life struggling for these heroes. With freezing weather for nine months every year, and temperatures even droping to minus 40 degrees Celsius, blackouts can become a nightmare for them. Therefore, heat pump is a vital requirement here while diesel power is not a cost-efficient choice for its expensive cost and logistics, and environmental pollution.

Therefore, here comes the AlphaESS Soldier, bringing a complete off-grid energy solution with solar energy storage and diesel generator, for the water heating system. This energy system includes 250kWp photovoltaics and 650kWh batteries. When the sun is shining brightly during the day, solar power will be turned into electricity to supply the basic appliances, and the excess power will be used to charge the battery for the nights or some snowy days.

Once the SOC reaches a pre-set value, the EMS will send a signal to the diesel engine, which acts as a backup power supply, to automatically initiate to power the loads and charge the battery to a set point. This entire system guarantees an uninterrupted power supply 7/24 hours.
