• Temperature of the batteries (colder batteries provide fewer amps).
• Age and condition of the batteries (older batteries lose AH capacity).
• Compliance with turning off unnecessary AC loads.
• Use of DC appliances and compliance with turning off unnecessary DC loads.
4.3 Battery Wiring Examples
In renewable energy systems, batteries are connected to each other in one of three ways:
•
Series (voltage increases, amperage stays the same as a single battery)
•
Parallel (voltage stays the same as a single battery, amperage increases)
•
Series/Parallel (both voltage and amperage increase)
