Our residential hybrid energy systems are for residential rooftops-including farm roofs, villas, sunrooms, neighborhoods, and all other residential rooftops-most of them have an installed capacity ranging from 3 kW to 50 kW. They connect to the public grid through voltage levels of either 220 V or 380 V.
Integrated Household Solution: The integrated household solution of Huijue is a comprehensive service program with efficient hybrid power generation, reliability and safety, intelligent operation, and maintenance. It provides one-stop and worry-free service for the investors of households, installers, and agents.
It combines solar panels and batteries with a wind turbine. This system is to ensure that there is a proper, continuous flow of electricity even when the solar panels do not produce enough electricity, such as at night, on a rainy or cloudy day.
Solar panels generate electricity when the sun is highest, and if the house doesn't require as much electricity at that time (for instance, no one being home and all the appliances off), the extra energy gets stored in batteries. In such a manner, this stored electricity can be used even if the solar panels are not producing when it is time to go home in the evening.
On the other side, wind turbines are able to produce electricity when there is wind, even light wind, at a wind speed from 2 to 3 m/s. That means that even when there is no sun, so long as there is enough wind, a wind turbine can work to power a house. When used in conjunction with a battery storage system, wind turbines can be used as a stand-alone energy solution, meaning that even in the absence of solar energy, homes can have electricity without having to worry about being able to.use appliances such as refrigerators, lamps, mobile phones, computers, etc.

It is made up of wind turbines and solar panels, from 1000 W to 5000 W, which, through an integrated controller, are changed into stable DC current. The current then goes through the battery bank and finally through the DC-AC inverter to provide clean electricity that powers your appliances.
Hybrid wind and solar systems of 5000 W and above are charged by solar and wind controllers. Wind turbines larger than 3 kW have a three-phase alternating current generator and hence they require an inverter to convert it to direct current.
1. Mode of operation with priority of the public network:
In this way, the system is coupled to the network, favoring the use of energy from the network to feed domestic appliances and can charge the batteries. The inverter, in this way, does not supply electricity to the grid, which means that it is not selling electricity to the grid.
In case of a power supply failure, the inverter automatically switches to solar energy.
During the night, in case the mains power comes back, the system continues using the electric supply. In the absence of solar or electric power, the system automatically switches to battery power. The mode is appropriate for the use of solar energy storage systems as a backup energy source and therefore designed for relatively low capacity and a number of solar panels and batteries, as well as low cost.
2. Battery Priority Operation Mode:
This mode is essentially the reverse of the network priority mode, where the hybrid inverter gives priority to using the battery. If the system has solar panels, it will be configured to charge the energy from the sun into the battery first, before using that energy.
At night, in case the batteries are low — say, voltage of a 12 V battery drops to below 10 V — then the system will tap power from the network to charge up the batteries.
3. Custom Operating Modes: The new feature in our hybrid inverter allows one to set a percentage factor; the system shall first give priority to 30-50% of the solar energy for direct use on household loads, then charge the batteries.
