Appendix I: 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)
