About rotating beacon light batteries

Since the input energy rotating beacon light of photovoltaic power generation system is very unstable, so generally you need to configure the battery system to work. Generally lead-acid batteries, Ni-Cd battery, Ni-H batteries. Choice of battery capacity rotating beacon light 12v in general should follow the following principles: First, to meet the premise of lighting at night, the daytime solar energy stored in the battery pack down as much as possible, but also capable of storing electrical energy to meet the needs of consecutive rainy days of night lighting. rotating beacon light battery capacity is too small can not meet the needs of beacon strobe light  at night, the battery is too large, on the one hand the state of the battery power is always in deficit, the impact of battery life, while wastage. Batteries should match the solar electricity load (lights) phase. A simple method can be used to determine the relationship between them. rotating beacon light battery power must be higher than the load power more than four times the system to work properly. Solar cell voltage exceeds the warning signal light  working voltage of 20 to 30%, in order to ensure the normal negative charge to the battery. Battery capacity must be higher than the load daily consumption of more than six times better.
