How Should I Connect My First Solar Installation?
Asked by SolarWizard987
I'm setting up my first solar power system on my apartment balcony, and I could really use some help with the connections. Here's what I have gathered so far:
- 2 cables (25mm, 75cm)
- 3 cables (35mm, 1.5 meters)
- 2 Bulk 55amp batteries
- 1 Acdelco 72amp battery
- 1 Jinko 415-watt second-hand panel
- 1 PSTAR 60a PWM regulator (handles 12/24/36/48V)
- 1 Changi 3000w inverter (12V) Could someone guide me on the correct order to connect these components? Also, is there anything else I might need? Thanks for your help!

To connect your system, start with the batteries: connect them to the PWM regulator first. After that, link the solar panel to the PWM. Finally, attach the inverter to the batteries. Regarding your three batteries, it's a bit unusual for a setup like this unless you intend to use them in parallel. Make sure they're fully charged and have matching voltages if you want to use all three together!

Two important things to keep in mind: First, check if your batteries have the same chemistry—are they all lead-acid? Second, clarify your goal. Are you planning to run appliances solely on the inverter, or do you want to feed energy back into the grid? If it’s the latter, you’ll need a specific grid-tie inverter.
NewbieNerd14: I'm not sure about the chemistry, but the labels mention 'lead acid,' and I just want to store energy for my appliances.

CuriousCat42: I picked up the extra batteries because I found a deal for the Bulk brand and got the Acdelco as a gift. Just wanted to mention them in case they were useful!
