1 When using it or test, the battery is on the south-facing solar panels, and as far as possible with the ground at a 45 degree angle, should be flat on the board or on The interior where the sun does not direct, it will affect the battery plates power generation
2 set of solar panels to be fixed in order to prevent being blown down by strong winds, affect use.
3 Do not cover the solar panels above the debris, leaves or plot thick dust, etc. Please clean up, so as not to affect the power generation efficiency of solar panels.
4. Use solar panels to charge the battery to make use of the controller (or anti-kickback diode) to prevent damage to the battery saturated cells and solar panels, solar panels generate direct current, for the exchange of electrical appliances connect using the inverse the inverter transformer to achieve the effect.
5. 20w watt solar panel can charge 7 - 17ah battery, charging 20 watts for one day or other electrical loads using a 4 - 8 hours, if the weather is not good use of time will be shortened
6. Can last more than 20years if handle properly.
