Grid-connected wind and solar complementary systems.
A grid-connected system is an integrated energy conversion and storage system. Wind turbines and photovoltaic panels capture wind and solar energy, respectively, and convert them into DC power. The inverter converts the DC power into AC power to meet the requirements of the grid. The controller acts as the brain of the system, precisely regulating the operation of each component to ensure efficient and stable energy conversion. The battery acts as an energy storage unit, storing power when there is a surplus of energy and releasing it when there is a peak in demand or a shortage of energy to balance the load on the grid. The whole system works together to realise grid-connected renewable energy generation, providing clean and sustainable energy support for the power system.

This canal flows day and night – I never thought it could make money. After Greef installed the system, it runs by itself. Every day I check my phone to see how much electricity was generated and how much I earned. I'll recover my investment in less than a year, and after that it's pure profit.
Since installing this variable-pitch wind turbine, the battery hasn’t run low again. Before, I used to worry whenever we had consecutive overcast days and light winds in the winter, but now it can even charge the battery in low winds. Best of all, it doesn’t suddenly start screeching during gusts, so it doesn’t disturb my family’s sleep. The installer also mentioned that variable-pitch turbines are easier to calibrate than fixed-pitch ones. I give it five stars!
“I built a small pico hydro system on the creek behind my off-grid cabin. The water head is only 3 meters and flow rate around 0.2 m³/s – too low for most generators. This axial flux coreless unit starts generating usable power at just 150 RPM. No cogging, no iron loss, and it’s silent. I’m getting 300-400W continuously, 24/7. My old induction generator would barely light an LED at that speed. Absolutely perfect for low-head hydro.”
