Solar Charging Controller SR 300-24 Duo Digital

Article-No. 6615

Offroad

For Solar Modules with:

max. 300 Wp Module Capacity

max. 10 A Module Current

max. 50 V Module Voltage

Operating Voltage: 24 V

Charging Options:

1 Supply- and 1 Starter Battery

Description

Please notice, that the device is only suitablte for solar panels up to the maximum power (Wp) and below the maximum persmissable voltage (Voc). In addition the controller is not suitable for an input-side connection (+/- solar panels) of wind, water, fuel or motor generators, power supplies, batteries or other current sources.

Main Charging Port I: Automatic charging and conservation of charge of the (main) board supply battery
Auxiliary Charging Port II: Current and voltage reduced for recharging as well as trickle charge of the vehicle’s starter battery, thus ensuring continuous starting capacity
Continuous control, full batteries by immediate recharging in case of current consumption
Automatic charging programs adjustable for gel, acid/lead-acid and AGM/fleece batteries
Indicators for operating state "Full", "> 80%", "Charging", "StandBy" and "Low Voltage"
Least own electricity consumption
Connection for Battery Temperature Sensor

Charging Programs

	„Gel“: Charging Program for Gel Batteries, Characteristic Line IU1oU2 Adapted to closed, gas-tight gel/dryfit batteries with determined electrolyte, which are generally requiring a higher charging voltage level and longer dwell times U1 to achieve short charging times with particularly high capacity storage and to avoid total discharge. Also recommended for EXIDE MAXXIMA a high-current battery in AGM filament technology.
	„AGM“: Charging Program for AGM/Fleece Batteries, Characteristic Line IU1oU2 Adapted to charging closed, gas-tight AGM (absorbed glass mat) batteries and batteries in lead-fleece technology requiring a particularly high level U1 with adapted dwell times for full charging and after that a moderate level U2 for trickle charge (round cell and plate technology).
	„DIN 0510“: Charging Program for Lead, Acid/Lead-Acid Batteries, Characteristic Line IU1oU2 General characteristic line DIN for charging and conservation to charge of open and closed lead storage batteries with removable cell plugs and possibility of acid level control and acid level correction (maintenance). Also suitable for recently developed, closed battery types (low-antimonous, with lead-silver alloy, calcium etc.) with low and very low water consumption. Allows short charging times with high level U1, high charging factor and high acid mixing, even during stationary application (acid accumulation) of "wet" drive, lighting, solar, heavy duty and standard batteries.
	„UNIVERSAL“: Charging Program for Lead, Acid/Lead-Acid Batteries: Characteristic Line IU1oU2 Universal program for charging and conservation of charge of acid batteries in vehicles (mixed operation mobile/stationary). Still offers short charging times, good charging factor and good acid mixing with average level U1 for open and closed, low-maintenance, maintenance-free standard, drive, lighting, solar and heavy duty batteries.
