Ancillary equipment in off-grid systems
Batteries can be the most expensive part of an off-grid system, because their working life is limited and they may have to be exchanged several times during a off-grid system is in operation. In most cases, batteries with lead-acid technology are used and it is important to select high-quality cells whenever possible.
To prevent the batteries from over-charging or over-discharging, electric controllers are needed. Many wind turbines for off-grid applications are already delivered with a matching controller. Inverters change the DC current generated by wind turbines into the AC current.
