3KW 5KW Off-Grid Hybrid Solar Inverter with WIFI Monitoring for Home Energy Storage

New Upgrade Small Size MPPT Solar Charge Controller 12V/24V 30A 40A 50A 60A 100A Current Auto Focus MPPT Tracking Charge with LCD Display Dual USB Solar Regulator Charge Controller Multiple Load Control Modes

OS-BLC series is the strongest current focus tracking MPPT, and has the national solar practical invention certifcate, product appearance certificate and related certification. For a new technology to be recognized by everyone, it needs users to use and compare. This product is to track the current focusing on the highest power point of the MPPT to adjust the internal charging method, so as to maximize the conversion of light energy into electrical energy.

  • 【Multi-function LCD Displays】This controller is 12V/24V automatically adapt,first connect the battery,then connect the solar panels,when you first use it, make sure the battery has enough voltage,so that the controller can recognize the correct battery type.
  • 【Reliable Protection】Overvoltage, Short circuit, Overload, Overcharge, Over discharge protection function; Automatic focusing MPPT tracking charging, high charging efficiency, Non-stop detection during charging, bidirectional focusing tracking.
  • 【Industrial-grade Master Chip】16AD sampling accuracy, temperature Charging current, discharge current accurate real-time display, power generation at a glance.
  • 【Dual USB MPPT Solar Charge Controller】 Using innovative MPPT technology high tracking efficiency up to 99%; Please refer to the information if you are not familiar with Mppt technology:There are many kinds of MPPT technology,Our Solar Controller Mppt technology is to detect the maximum charging current,not the boost type or the automatic charging of the solar panel voltage.

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.
