In well-developed solar markets, there is a large range of different battery voltages (2V-12V) and Ah ratings (more than 4000Ah) that make possible a variety of battery bank designs. In less developed markets only 12V deep-cycle batteries may be available and as PV system sizes increase so will the number of parallel strings. It is also often the case that certain inverters and charge controllers are not available in 48V designs. In any case, it is ideal to keep the number of parallel strings to 3 or less if possible as ensuring balanced charging and discharging becomes more complicated with each additional parallel battery string.
