ECOSUN ES-EXPERT CC2024 charge controller PWM 20A for 12V and 24V batteries, with automatic voltage recognition and full protections. Accepts panels up to ~216 W at 12V.
Ο ECOSUN ES-EXPERT CC2024 charge controller is a PWM 20A charge controller for 12V and 24V batteries. It recognizes the battery voltage on its own, charges it correctly and protects it. It is a Greek product of ECOSUN, with technical support and spare parts in the country.
PWM is the simple, cheap and very reliable solution for small autonomous systems: lighting, caravan, boat, pump, street lights. It has less to break and costs much less. Above 150-200W it is worth looking at MPPT controllers.
With 20A charging current, it accepts panels up to approximately 216 W in a 12V system or up to
432 W at 24V. Do not reach the limit: leave a margin of 20-25%, because a panel in cold and
On a clear day it gives more than its nominal power.
The order matters and is often wrong: first the battery to the regulator, after the
panels, lastly the loads. This is how the regulator reads the voltage and understands whether it is working at 12V or 24V.
On disconnection, vice versa. See also solar panels And the
deep discharge batteries that match.
Most problems are not regulator failure, they are installation problems. Three that we see all the time:
thin cable between regulator and battery, which heats up and drops the voltage; lack of safety in
positive of the battery, so a short circuit has nothing to stop it; and regulator closed in
box without ventilation, which constantly works in overheating and drops the charging current on its own. Give it
room to breathe and a cable of the correct cross-section and it will serve you for years.
