This combined solution is designed for smart energy management at higher latitudes, inconsistent seasonal yields or unreliable grids. In times of high solar yield the PV and battery provide all the requirements of the lamphead. Surplus energy can power other applications and buffer the grid during demand peaks. When solar yields are lower, energy is drawn from the grid to feed the battery. Energy feed in and out is smartly controlled for a zero cost seasonal balance and can even generate profit - sell for a dollar, buy for 70 cents.
