【HIGH TRACKING EFFICIENCY】- HQST 12V 40 amp solar charge controller adopts advanced MPPT technology that ensures fast and stable track of the maximum power point, high tracking efficiency of up to 99%, and peak conversion efficiency of 98%. Maximizing the energy from solar panels to charge your system. It auto-detects 12V or 24V DC system voltages. The max load output current is 20A. If it exceeds the 20 amp DC load (240 watts), the over voltage protection will turn off the output.

【PARALELL CHARGE FUNCTION】- 2 HQST MPPT controllers of the same series(M2420N/M2440N/M4860N) can work together to charge the same battery with the parallel charge cable (not included), to meet high power charging requirements and 2 controllers should set the same battery pack voltage. Our negative grounded controller offers overcharging/over-discharging/overload/overheat/short circuit/reverse protection. The maximum degree avoids the damage due to system fault or installation error.

[Cable composition] Contains 2 pairs of solar connectors. A pair (1 black + 1 red) 20FT 10AWG solar extension cord made of pure copper and tin coating.

[Female/Male connectors] Two cables, one end of which is connected to the Solar panel, and the other end can be connected to an Adaptor Kit Solar Cable. You can also remove the connector from one end and connect the cable directly to the charging controller.

【Enhanced Performance with 9 Busbars】Experience superior performance with the leading 9 busbars technology. This advanced design minimizes the risk of microcracks, ensuring a longer service life compared to conventional 5-busbar designs. Also, it effectively lowers the module's working temperature by approximately 2℃, further optimizing its overall performance.

【Higher Efficiency, More Power Output】With Grade A+ 166mm large monocrystalline solar cells, this panel achieves a remarkable 22-23% conversion rate, outperforming conventional options. It generates up to 500Wh of electricity per day with 5 hours of direct sunlight. Unleash the potential of solar energy with our high-performance panel.

【Extremely Flexible】- With good flexibility, this solar panel is perfect to be installed on any off-grid living space with curved surfaces such as roofs, campers, trailers, boats, cabins, sheds, tents, yachts and more. 6 pre-drilled mounting holes allow you to secure this flexible solar panel much more easily.

【9 Busbars Solar Cell】- Upgraded with 9 busbars (BB) solar cell, HQST solar panel provides high conversion efficiency up to 23%. The narrower busbar space and more cells receiving surface bring lower cost and increase the output of the PV module. Compared with 5BB panel, HQST solar panel ensures lower risks of microcracks and longer service life.

【High-Efficiency】- 100W monocrystalline solar panel with a high conversion efficiency is up to 21.8%. Bypass diodes can ensure excellent performance in low-light environments. Perfect for off-grid 12 volt battery charging system and a variety of DC applications.

【Long Lifespan】- 100 Watt solar panels use advanced encapsulation material with multi-layered sheet laminations ​to enhance cell performance and provide a long service life. Guaranteed positive output tolerance (0-3%). 100% EL testing for all solar modules, guaranteed no hot spots.
