Victron's range of PWM and MPPT charge controllers are both widely used to charge batteries with solar power.
The PWM controller is in essence a switch that connects a solar array to the battery. The result is that the voltage of the array will be pulled down to near that of the battery.
A PWM controller is not a DC-DC transformer. The PWM controller is a switch which connects the solar panel to the battery. When the switch is closed, the panel and the battery will be at nearly the same voltage. Assuming a discharged battery the initial charge voltage will be around 13V, and assuming a voltage loss of 0.5 V over the cabling plus controller, the panel will be at V PWM = 13.5V.
The voltage will slowly increase with increasing state of charge of the battery. When the absorption voltage is reached the PWM controller will start to disconnect and reconnect the panel to prevent overcharge (hence the name: Pulse Width Modulated Controller).

Liquid crystal display:
For status monitoring and set-up
Load Output:
Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage. Some loads (especially inverters) can best be connected directly to the battery, and the inverter remote control is connected to the load output. A special interface cable may be needed, please see the manual. The connect and disconnect voltages are adjustable.
Day/Night Timing of the Load Output:
This option allows for a pre-set ON-time after dusk.
Programmable Battery Charge Algorithm:
Preprogrammed algorithms for AGM, GEL, Flooded or LiFePO4 batteries (with internal BMS only)
Two 5 Volt USB Outputs:
Maximum current (both outputs combined): 2A
Applications:
Marine
RV's
Caravans
Off-Grid Systems
Tiny Houses
Cabins
