PV Battery Systems
with Steca inverters.
In contrast to solar home systems, stand-alone
systems are equipped with an extra inverter.
This extra inverter changes the direct current of
the battery into alternating current. This means
that any common AC appliances can be used -
just like with the public grid. However, DC appli-
ances can also be connected to the output of the
charge controller.
The inverter is connected directly to the battery,
using a cable which is as short and as fat as pos-
sible. An AC system can be created with a system
or battery voltage of 12 V, and also with 24 V or
48 V for greater capacities. This concept makes
installation quick and easy.
