The aim of VONSCH was to complete its photovoltaic portfolio and to produce highly reliable battery charger with high efficiency and long durability.
Solar MPPT charger FOTO CHARGER DC 48 uses DC voltage generated at the terminals of solar panel to optimal and efficient charging of batteries with a nominal voltage of 48 V.
The charger is powered directly from DC voltage of photovoltaic panels connected in series into a single string. Integration of several FOTO CHARGER DC 48 chargers to allow faster charging of the battery is possible, when higher power of properly connected panels is present.
In case of insufficient illumination of solar panels and discharged battery, it is possible to charge the battery from the grid by adding the rectifier module UM-01AC to FOTO CHARGER DC 48.
Reliable and efficient charging is ensured by 3-stage charging characteristics.
The advantage of FOTO CHARGER DC 48 is low acoustic noise, high efficiency and the possibility of integrating new promising features.
The main advantages of using FOTO CHARGER DC 48:

Accessories
Rectifier module UM-01/230AC rectifies single-phase input voltage 230 V AC, 50Hz, to output DC voltage to
power the FOTO CHARGER DC 48 charger. Combining the rectifier module UM-01/230AC and FOTO CHARGER DC 48 charger,
grid charger is created. The requirement to recharge the battery from electrical grid is based on long-term low light
state of solar panels and discharged battery.
To access the Internet, it is necessary to ask for the public IP address at your Internet service
provider or administrator and configure redirection in the local router.
