It is better to install controller in the room. If install the controller outside, please keep the environment dry, avoid direct sunlight❖ The controller will be hot in process of working, please keep the environment ventilation, away from flammable.❖ The Voc of solar panels is high (especially 24V/48V system, please take care❖ The battery had acidic electrolysis, please put on goggles during installation. If you accidentally exposed to electrolysis, please rinse with waterThe battery has huge power; prohibit any conductor short circuit the positive and negative pole of battery. Suggest to adding a fuse between battery and controller. (Slow motion type, the action current of the fuse should be 1.5 times rated current of controller:)ldsolar BestQuality Best Unboxing video Supplier Factory,After-sale Service——Free replacement for 1.5 ~ 3 years

MPPT solar charge controller introduction videoMPPT has in many ways revolutionized the PV industry. Higher-voltage PV arrays can now be used, reducing wire cost, improving efficiency, and increasing array performance under less-than-ideal conditions (clouds, low-horizon sunlight). But what exactly is MPPT, and how does it work?Take a 12 V PV module, put it out in the sun, and measure the open-circuit voltage (Voc)—it will be much higher than 12 V, likely approaching 20 V. The reason that “12 V” nominal modules need to produce more than 12 V is that its voltage is the electrical “pressure” in a circuit, and has to be higher than the battery voltage to “push” energy into those batteries. PV modules perform best at cold temperatures, but their voltage will decrease as they get warmer—by about 0.5% per degree centigrade. A “12 V” nominal battery will rise to more than 14 V as the batteries approach a full state of charge. Higher PV voltage is essential, especially in hot weather; to pu...

LDSOLAR upgrades the Clear protection paint process for all MPPT controller productsThe three-proof paint process refers to coating a layer of polymer film to completely cover the outline of the printed circuit board, thereby providing protection to the circuit board components. After the electronic circuit is coated with the three-proof paint, it can prevent the corrosion of moisture, dust, chemicals and extreme temperatures. If it is not sprayed (no protection), it can cause damage or malfunction of electronic components. When the controller is in a humid and dusty environment, it is necessary to get better protection, LDSOLAR in the MPPT controller production process, coating the circuit board with three-proof paint, can effectively improve the product to work in harsh environments, and effectively reduce The failure rate of the product.In this video, we will introduce how ldsolar sprays the three-proof paint on the solar controller
