Frequently Asked Questions

Q: What is an AC Coupled Storage system and how does it differ from DC?

An AC coupled system connects to the AC side of your existing solar inverter. This makes it ideal for retrofitting existing PV systems without needing to replace your current inverter, providing a simpler and more flexible installation process.

Q: How does the 10ms auto-switch benefit my home electronics?

Most modern electronics and computers can withstand a very brief power interruption. A 10ms switch is so fast that your lights won't flicker and your devices won't reboot, ensuring continuous operation during a grid failure.

Q: Can I increase the battery capacity in the future?

Yes, the system is designed to be expandable. You can start with a 5.12 kWh kit and scale up to 20 kWh by adding more battery modules as your energy needs grow or as you add more appliances to your home.

Q: What is "Peak Shaving" and "Valley Filling"?

Valley filling is charging your batteries when electricity rates are lowest (off-peak). Peak shaving is using that stored energy when rates are highest. This automatic process significantly lowers your monthly electricity bills.

Q: Is the LiFePO4 battery chemistry safe for indoor residential use?

Absolutely. LiFePO4 (Lithium Iron Phosphate) is widely regarded as one of the safest lithium chemistries due to its high thermal stability and resistance to overheating, making it perfect for home energy storage.

Q: Does this system work with any existing solar panel brand?

Because it is an AC Coupled system, it is compatible with almost any existing residential PV setup regardless of the panel brand, as it integrates with the AC output of your current inverter.
