Rain Bird ISM-9 Solar Controller: Standard Wiring, Check Rain Bird Site

Hooking Up a Rain Bird ISM-9 24V Solar Controller

Retired pipefitter, installed regular systems, never solar. ISM-9: 25.5 VAC in/out to valves. What's needed?

Standard Valve Wiring

All 24VAC controllers wire the same:

• Common wire (white) → common terminal → daisy-chain to all valves.
• Zone wire → zone terminal → one valve each.

Solar Specifics

Panel, battery, charge controller likely integrated. For wiring details: Rain Bird timer literature.

Hookup is standard—just power source differs.
