Load Controller

The load controller is discussed in more detail in Chapter 12. It optimizes and con­forms to the transfer of photovoltaic energy generated by the modules in order to match consumption needs. It also protects the battery against excessive overchar­ging and overdischarging.

6.7.1 Battery Bank

Banks of batteries accumulate the electric power generated during the day, making it available whenever necessary. They usually consist of lead-acid deep-cycle bat­teries, preferably sealed and possibly with no need of water replacement (although those batteries are more expensive), with a nominal voltage rated at the dc-link voltage. Further details of battery banks, maintenance, and sizing are provided in Chapter 11. A battery bank also requires a healthy monitoring system to indicate the state of charge and to support the maintenance.
