What precautions should I take before installing/adding Stackable Micro Battery?

When installing/adding expansion batteries, it is necessary to power off and shut down the system to protect yourself and the machine. Performing this operation while powered on is not covered under warranty. Please follow the steps below for proper installation: a. Disconnect the Micro Storage Unit and the solar panels. b. Press the on/off button for 2 seconds to turn off the power. c. After turning off the Micro Storage Unit, install the expansion batteries to the Micro Storage Unit. d. Connect solar panels for normal use.

Are there any other precautions that need to be taken when installing and using the product?

Ensure that the AC outlet is properly grounded.

Can I change the battery to the Micro Storage Battery or Stackable Micro Battery by myself?

No. If your battery in Micro Storage Unit or Stackable Micro Battery does not work or working conditions do not meet expectations, please contact the TSUN customer service team for further help.

How to make sure the equipment is safely grounded?

The included AC end cable already ensures that the machine is safely grounded, so there's no need to worry.

Are microinverters required to use Micro Storage Unit?

Micro Storage Unit does not require a microinverter. A microinverter is already incorporated into its all-in-one design that also includes a photovoltaic controller and energy storage battery pack.

Can the Micro Storage Unit charge batteries using the household power grid?

Yes, the Micro Storage Unit can charge your batteries using your home's AC power. It can be scheduled to do so during off-peak hours to reduce costs, and will also automatically charge AC power when the batteries are low and there is insufficient solar power, preventing battery damage and ensuring that you have some reserve energy available.

How do I use Micro Storage Unit to achieve zero-power function?

You need to buy our optional accessory smart meter, which prevents energy back-flow to the public grid by adjusting the output power of the Micro Storage Unit, matching household load in real-time. This achieves the purpose of not transmitting energy to the public grid, which is the anti-back-flow function.

How does the smart meter help Micro Storage Unit achieve zero energy waste?

The smart meter detects the total household electricity consumption, which lets Micro Storage Unit continually adjust output power. It's real-time and precise electrical discharge for your home, helping you achieve efficient energy use without waste.
