Product description

PWM solar regulators connect the solar panels directly to the battery to be charged and after reaching a certain battery terminal voltage, the charging is regulated by pulse current limitation.
They are therefore suitable for panels with the same system voltage as the battery voltage, otherwise, losses occur where part of the potential power is lost due to inappropriate V-A characteristics of the panel.
More sophisticated regulators allow adjustment of operating parameters or the type of battery being charged, simple regulators have parameters set fixed for the most commonly used lead acid batteries.
The Win300 regulator belongs to the group of PWM solar regulators, allowing setting the type of battery to be charged (Pb AGM, Pb GEL, Pb WET, Pb Calcium, LiFePO4, Li-Ion, LTO).
This also determines the relevant operating parameters.
The Win300-NBT is also equipped with Bluetooth technology for wireless setup from a mobile phone.
Primarily, these regulators are designed for operation in mobile devices such as caravans or boats.
