Overview Blue Sky Energy’s Sun Charger 30 (SC30) solar charge controller charges 30A for 12V-nominal batteries. The SC30 uses precise PWM charge voltage control combined with a sophisticated multi-stage charge algorithm to optimally charge flooded, GEL, AGM lead-acid, or Lithium chemistry batteries. To periodically condition flooded lead-acid batteries the SC30 will also perform a manual or automatic Equalization charge. The SC30 is fully programmable, through the onboard display is possible to program the charge profile for any type of Lead-Acid and Lithium batteries and gmonitor real-time data from battery and solar array. Features:PWM technologyMulti-Stage charge control (plus Equalization if enabled)Built-in digital display for real-time data and charge profile settingsFlush mounting (surface wall mount box optional ASIN: B08H9Z1YH6) Temperature compensated charge profile with battery temperature sensor ASIN: B007S3HWDAFully programmable for any type of Lead-Acid or Lithium batteries Made in the USA5-Year Warranty Specification: Max.
