Rich Solar RS-i4 DC Isolator Switch
The Rich Solar RS-i4 DC Isolator Switch provides a secure way to disconnect DC power between your solar array and downstream equipment. Built for outdoor use, it is designed for on-grid and off-grid solar applications where safe isolation, fast shutoff, and reliable installation matter.
Fast DC Disconnection
Quickly disconnect DC power from the solar array to the charge controller, batteries, or inverter when maintenance, shutdown, or service access is needed.
SAFE-LOCK Operation
The isolated SAFE-LOCK handle uses three rotational positions to help reduce tampering and support more controlled solar system operation.
Outdoor Solar Ready
Built for outdoor solar electrical installations and suitable for both off-grid and on-grid applications.
Product Overview
The Rich Solar RS-i4 DC Isolator Switch is designed to safely isolate DC power in solar energy systems. It helps create a more serviceable electrical layout by allowing the solar array to be disconnected from charge controllers, batteries, inverters, or other downstream components.
This model is built for 4-pole and 2-string applications, making it a practical choice for solar systems that require a larger DC isolation setup than a basic single-string disconnect. Its input and output connections are designed for easier installation, while the lockout option adds another layer of control during service or system shutdown.

Best Uses
- Disconnecting DC power from a solar array
- 4-pole and 2-string solar isolation setups
