Bulk Solar Charge Controller Products Description 聽聽 Can I use 24 volt solar panels to charge 12 volt batteries through MPPT controller? 聽 Yes, you could do it. The voltage isn't too much of a concern, it is the current the panel can provide. What is commonly known as a 12V panel is usually a 36-cell module with an open-circuit voltage of 22V, making maximum power at 18V. 聽聽 Can you oversize a MPPT charge controller? 聽 yes, some higher quality MPPT solar charge controllers such as those from Victron Energy let you oversize the solar and put up to 750W on a 20A unit. Just be careful not to go over the INPUT current limit of the charge controller. Can you run 2 MPPT controllers together? 聽 Yes you can have 2 (or more) MPPTs on the same battery bank. If it was not possible, you would never be able to have, more panels, than can be handled by 1 MPPT, in 1 system. 聽 Maximum Power Point Tracking(MPPT) Solar Charge Controller is aphotovoltaic (PV) charge controller that tracks the maximum power point of a PV array to deliver the maximum available current for charging batteries. The charge controller can be used with 12 and 24 DC battery systems , Max PV input 100V. 聽 System Voltage12V/24V PV Max Input Voltage100V PV Max Input Power12V 390W锛?4V 780W Self-consumption鈮?3mA Max Charging current30A Max Discharging current30A LVD11.0V ADJ 9V鈥?12V锛浢?/24V LVR12.6V ADJ 11V鈥?13.5V锛浢?/24V Float Voltage13.8V ADJ 13V鈥?15V锛浢?/24V锛?/p> Boost Voltage14.4V 锛?脳2/24battery voltage less than 12.6v restart boost 2hours Battery Over Voltage Protection16.5V 锛浢?/24V Reverse Connection ProtectionYes Load Over Current ProtectionYes, each 30s auto restart again Controller Over Temperature ProtectionYes Charging TypeMPPT Temperature Compensation-24 mV /鈩?for 12Vsystem 锛浢?/24V锛浢?/48V Working Temperature-20鈩冣€?55鈩?/p> Terminals scale16mm2 Waterproof gradeIP32 Size200mm*183mm*54mm New weight1.2KG 聽Bulk Solar Charge Controller website:http://www.ybysolar.com/solar-charge-controller/
