If you’re using the MyGrid 10K power system, it’s important to understand how it behaves while charging—especially when deciding between 120V and 240V AC input.
Many users assume they can use the system while charging on any input, but that’s not always the case.
Can the MyGrid 10K Be Used While Charging?
The answer depends on how you’re charging the system.
❌ Charging via 120V AC Input
When charging your MyGrid 10K using 120V AC input:
- The system cannot be used simultaneously
- Output to connected devices is disabled during charging
👉 This means you won’t be able to power appliances or devices while the unit is charging through 120V.
✅ Charging via 240V AC Input (Power Relay Mode Enabled)
When using 240V AC input with the Lithium 6ft Super Charging Cable, the MyGrid 10K supports a special feature called:
What Is Power Relay Mode (UPS Feature)?
Power Relay Mode, also known as UPS (Uninterruptible Power Supply) mode, allows your system to:
- Deliver continuous power to connected devices
- Pass electricity directly from the wall outlet
- Charge the unit at the same time
How Power Relay Mode Works
In this mode:
- Your devices are powered directly from the AC source (wall outlet)
- The MyGrid 10K charges in the background
- Power delivery remains seamless with no interruption
This setup is ideal for:
- Home backup systems
- Critical electronics
- Situations where continuous power is required
Why Power Relay Mode Matters
Using Power Relay Mode provides several advantages:
- ⚡ No downtime for connected devices
- 🔄 Smooth transition between grid and battery
- 🔌 Efficient pass-through power delivery
- 🛡️ Added protection for sensitive electronics
Key Requirements for Power Relay Mode
To enable this feature, you must use:
- 240V AC input
- Lithium 6ft Super Charging Cable (required)
Without this setup, Power Relay Mode will not activate.
Final Thoughts
Understanding how your MyGrid 10K operates during charging is essential for maximizing performance and avoiding confusion.
- Use 120V if you only need to charge the unit
- Use 240V with the proper cable if you need simultaneous charging and power output
For the best experience—especially in backup or critical power situations—240V charging with Power Relay Mode is the recommended setup.
