Solar and battery storage systems should always be installed by a licensed electrical professional. Before purchasing any equipment required for a solar battery (hybrid) or off-grid power system, it is very important to understand the basics of designing and sizing energy storage systems.
As solar battery systems became larger and more advanced, AC-coupled systems emerged as one of the best configurations due to the low cost and ease of installation of string solar inverters. Most modern off-grid AC-coupled systems utilise bi-directional inverters, often paired with one or more compatible solar inverters.
The most important part of designing any off-grid solar or battery system is calculating the daily energy requirement in kWh. For grid-connected sites, detailed load data can often be obtained directly from your electricity retailer or by using meters to measure the loads directly.
Proper cable sizing is critical in solar and battery installations for ensuring system efficiency, safety, and reliability. The cables used must safely handle the expected current, minimise losses, and be protected from potential overcurrent situations. As explained in this section, below are the three key steps to correctly sizing cable:
