Advantage of  30A 40A 50A 60A 100A MPPT Solar Charge Controller:

1. Dual-wave or multi-peak tracking technology, when the solar panels are shaded or some of the solar panels are damaged, multiple peaks will appear, and the controller can still accurately track the maximum point power；

2. Using advanced digital power technology, the circuit energy conversion efficiency is as high as 98% ；
3. The combination of various tracking algorithms can accurately track the best working point within 1 second, and the MPPT tracking efficiency can reach up to 99.9%；
4. It has a current-limiting charging mode. When the power of the battery panel is too large and the charging current is greater than the rated current, the controller automatically reduces the charging efficiency and makes it work at the rated charging current.

Multiple input methods

R5.0 solar charging DC socket.
R5.0 DC lamp output DC socket.
Easy connection and low heat generation.

Smart large screen console

LCD display, adjustable charging and discharging parameters, more convenient.

Take care of the battery

Complete 3-stage charging management, effectively protect the battery, the battery is more durable.

Multiple layers of security protection

1. Short circuit protection 2. Open circuit protection 3. Overcurrent Protection
4. Overcharge protection 5. Over discharge protection 6. Reverse polarity protection

OS-BLC Series MPPT Solar Charge Controller FAQs


Q1. How many watts (W) of solar panels can be connected?


A1. 30A Within 360W, 40A Within 480W, 50A within 600W, 60A within 720W, 100A within 1200W.


Q2. Does this controller support lithium batteries?


A2.  The new controller can be used for lead-acid batteries and lithium batteries. If you charge lithium batteries, you must set the charging parameters after connecting to the power. Please refer to the manual for details.


Q3. My solar panel is 36V 200W, can I charge 12V battery?


A3. To charge a 12V battery, the working voltage of the solar panel can be between 17V and 23V, and for a 24V battery, the working voltage of the solar panel can be between 36V and 46V.


Please make sure that the working voltage of the power supply and solar panels are within this range. If it is too high, the controller will be damaged.


Q4. Can the inverter be connected to the load side of the controller?


A4. Please connect the inverter directly to the battery and not to the load terminal of the controller.


Q5. Does the controller have requirement for battery capacity?


A5. No, as long as the voltage corresponds to it (but the maximum current of the board and the battery capacity should correspond). For example, the current of the solar panel is 5A, the battery capacity is preferably 50 AH, the current of the solar panel is 10A, and the battery capacity is preferably 100 AH. Do not use a large board to charge a small battery, which may be dangerous.


Q6. How do you connect the solar panels, batteries, and controllers?


A6. Please be sure to connect the battery first (to ensure that the battery is fully charged), then connect the solar panel. When disassembling, please remove the solar panel first, then remove the battery, please connect it exactly as this order, otherwise the controller and other components probably damaged.
