Can refer to the following (in order to improve the national professional knowledge, completely free gold): 1, the calculation of battery capacity * E3 a* c @ J: $a; M, I/ G6 O4 l- B! The capacity of the battery is very important for ensuring the continuous power supply. Within a year, there is a great difference between the month of matrix generation. The square of the generating capacity of electricity can not meet the needs of the month to rely on battery power, give supplement; electricity required in more than month, is to rely on batteries to store excess energy. So the lack of matrix generation and surplus value, is one of the basis for determining battery capacity. The same load, continuous overcast and rainy days during the electricity must also be obtained from the battery. Therefore, the power consumption during this period is also one of the factors determining the battery capacity. Therefore, the battery capacity BC formula: BC=A * QL * NL * TO / CCAh (1) L I h U#}): T1 L$E0 T: | Type: A is the safety factor, from 1.1 to 1.4; NL is the longest continuous rainy days; 7 D; U H$L, w% JK! QL is the load on average power consumption, working current multiplied by the daily working hours; 4 A7 O- O1 U 0 M. n G2 C |); % a/ (m# U7 L [7] T* s! TO is the temperature correction coefficient, generally at 0 DEG to 1 DEG C, - 1.1, - 1.2 DEG C; CC is the depth of battery discharge, general lead-acid battery 0.75, alkaline nickel cadmium batteries 0.85. 2, the design of solar cell array W!
