The challenge here is the energy source. If a tracker is not permanently connected to the mains or to energy sources such as solar modules or small wind generators, it must have a reliable, weather-independent power supply. This must work reliably even under extreme temperature and humidity conditions, supply high peak currents for the modem and at the same time allow flexible adjustment of voltage and current.
VARTA Microbattery offers the technical solution for this: hermetically sealed, rechargeable Ni-MH button cells that have been specially developed for an extended temperature range from –20°C bis +85°C.
The recommended configurations – e.g. 3/V500 HT oder 4/V500 HT – can be individually adapted to customer requirements in terms of size and voltage.
