SMK Solar Battery Charge Regulators
SMK MPPT 30 amp Solar Charge Controller
For the medium-size solar systems up to 30 amps input. Automatically detects correct battery voltage, and gives the ability to monitor the system remotely, using RS485 port.
SMK MPPT Solar charge controller is an advanced maximum power point tracking (MPPT) battery charger for off grid photovoltaic systems.
Why choose this 30 amp controller?
- At least 30% higher solar harvest for power than PWM controllers
- Wider range of Solar PV voltage input 18 v – 100 v DC
- LCD and LED displays the output every second
- Large heat sink for excellent cooling, will not de-rate output
- Economical and non-corroding plastic casing
- Battery type and voltage can be easily set using the LCD screen.
Features：
- 12V/24V/46V/48V Battery auto detect, parallel design
- Multi-stage charging optimizes battery performance
- MPPT eficiency >99.5%, Peak conversion efficiency 97.5%
- Compatible with Gel. AGM. Flooded. Sealed lead acid and Lithium batteries
- Comprehensive protection
- Dual fan cooling design
- Easy installation and commissioning
- Monitor solar output online via RS485 communition, Ethernet/RS232 communication Optional
