A solar charger from the vario series is an MPPT charge controller designed to optimise the energy produced by photovoltaic panels and use it to charge batteries efficiently. MPPT technology continuously adjusts the operation of the photovoltaic generator to extract the maximum amount of energy, whilst ensuring the battery is charged correctly.
The vario series comprises two ranges:
- variotrack (vt): low-voltage solar chargers compatible with 12, 24 or 48 V battery systems.
- variostring (vs): high-voltage solar chargers designed for 48 V battery systems, allowing the use of photovoltaic strings of up to 900 V depending on the model.
It works together with the xtender or next series of inverter-chargers to build complete solar systems.
Directly compatible with our xtender series of inverter-chargers and our next series with the xcom 485i-nx for offgrid/ongrid installations.
It can also work alone in 12/24/48V systems for example, in a telecom system. The vario chargers have been used in standard solar systems as well in special applications (hydro, DC/DC converters, DC minigrid).
The vario chargers are compatible with all 12V, 24V, 48V (depending on the model chosen) battery chemistries (lithium, lead, Na+…), either communicating or not. A very flexible battery profile configuration helps you to adapt to each technology.
