How To Size Your Off-Grid Solar Power System
A good rule of thumb is that if your energy needs are less than 1,000 watts, go for a 12V system. If you use between 1,000 and 3,000 watts, then a 24V system is best.
ting the generator set and power system configuration for the cell tower. At the same time, t ere are certain loads that every base transceiver station (BTS) will use. These loads are pictured in Figure 2, which shows a typical one-line electrical layout for a base station employing a 12 kW (15 kVA)
The antenna output power level is typically between 20 watts and a few hundred watts for an outdoor base station. Television transmitters, by comparison, have 10-1000 times higher output power than outdoor base stations. Antennas mounted indoors use very low power levels, typically around a few watts or less.
Figure 2 - Typical electrical layout for loads on a telecom base station.As you can see, the load consists mainly of microwave radio equipment and other housekeeping loads such as lighting and air conditioning units. The actual BTS load used on the cell to
If you use between 1,000 and 3,000 watts, then a 24V system is best. If you require more than 3,000 watts, then you might even need a 48V system. The reason you want to raise the voltage for higher wattages is that it decreases the current that will flow through your system.
