IVT Charge controller PWM Serial 12 Seri

Compact and powerful. Reliable charge controller for solar systems up to 4 A. A straightforward and extremely reliable device for charging lead-acid and lead-gel batteries within smaller solar installations. It charges the battery using the PWM charging method. When the charging voltage is reached, the charging current is switched off, protecting the connected battery from overcharging. With a low self-consumption, this solar charge controller is extremely economical. Two LEDs indicate whether the battery is full or still charging.

The PWM charging method initially charges the battery with maximum current. Once the respective charging voltage is reached, the current flow is stopped to prevent overcharging. After this initial charging step, the battery is usually not fully charged yet. A drop in battery voltage is to be expected. Therefore, the charging current resumes when a defined voltage level is fallen below. This process repeats until the battery is fully charged.
