Quality Control
Battery Use and Maintenance:
1) Please use a constant-voltage charge.
1) Please use a constant-voltage charge.
2) In floating charge, the voltage is 2.23 to 2.27 per unit cell.
3) In cycle use, the voltage is 2.35 to 2.45 per unit cell, the max. Current is no more than 25%° C
4) Please do tighten the bolts to avoid sparkle and poor contact when the battery is in use.
5) Please do not use it near the heat source and open flame.
6) Please keep it at a low temperature. Please change it while there is liquid leaking or damage.

FAQ
Q：Many buyers ask us why the electrical current with the multimeter test can not reach the nominal current?
A：Because the short circuit current is a measure of the quality of the solar cell parameter, this parameter can only be tested with the component test, and the multimeter itself is the load, so the test parameter is the working current, please don't misunderstand. And the solar panel test conditions are irradiance 1000W/㎡, the ambient temperature is 25℃, AM1.5(atmospheric transparency), our solar panels are tested under the standard light intensity, is a theoretical concept, solar energy will be based on the buyer's region, the weather and the degree of pollution will moderate decline.
Q：How much power can solar panels drive?
A：This depends on the battery capacity of the customer terminal and the power of the inverter, which has nothing to do with our solar panels, our solar panels are only responsible for charging your battery, it does not store electricity itself, the solar energy is responsible for charging the battery, the battery discharges the electrical equipment, which is a charging and discharging process. Customers must understand some basic knowledge of electricians, so that they can go back to do DIY.
Q：Can solar panels work on cloudy days?
A：This concept is very vague, cloudy days need to see the intensity of the light, if the light is strong there will be weak
current and voltage, but compared with the bright light in sunny days tens to hundreds of times worse. In short, the stronger the light, the better the effect of power generation, the weaker the light, the worse the effect.
Q：How about solar panels without controllers?
A：Better use a controller! It's okay if you can't use it, but it depends on how you use it, the role of the
controller is only to control the relationship between solar energy and the battery and the load, protect the battery from
overcharging and overdischarging, short circuit protection, etc., and can only control the working time state of the load, etc., specific reference to the controller manual, in addition, the controller's load has current requirements, 10A controller generally its load is not higher than 12A current, correspondingly, 10A can drive electrical appliances below 120W, 20A can drive electrical appliances below 200W, 30A can drive electrical appliances below 500W, if not used, but there may be a problem of overcharging the battery, which will damage the battery. At the same time, overdischarge will also affect the life of the battery.
