Using SQ8W-100 Toggle Switches FOR Off-Grid and Hybrid Power Systems
Looking to create or upgrade your own solar or backup power system? The SQ8W-100 toggle switch is a must-have component for any DIY enthusiast working with off-grid or hybrid energy setups. Whether you’re powering a small cabin, setting up an emergency backup system, or experimenting with renewable energy at home — this switch gives you manual control, flexibility, and safety.
🔌 Switch Between Power Sources
Need to choose between solar, battery, or a diesel generator? The SQ8W-100 makes it easy.
- Seamlessly switch your inverter input between your battery bank and generator.
- Avoid running everything through expensive automatic transfer switches.
- Manually control your system — ideal for testing, maintenance, or just peace of mind.
Perfect for:
- Off-grid cabins
- Vanlife / camper systems
- Generator-powered homes
- Emergency power setups
☀️ Manage Solar Input Manually
Sometimes it’s just better to be in control — especially when dealing with solar energy.
- Use the SQ8W-100 to redirect solar power to different charge controllers or battery banks.
- Isolate your solar array for maintenance or during system faults.
- Quickly test panels, controllers or wiring by manually switching connections.
Pro tip: Label your switches clearly to avoid confusion when making changes under pressure!
💡 Charge Your Batteries at Night – BY Your Terms
If you’re on a night-time electricity tariff (like Economy 7 in the UK), charging your battery bank while rates are low makes perfect sense.
With a simple timer relay and the SQ8W-100, you can:
- Automatically charge your batteries from the grid at night.
- Switch back to solar or stop charging during the day.
- Manually override the timer whenever needed.
This combo helps you save money and protect your system from overuse — without relying on complex automation.
