frequently asked questions

How many systems are able to connect in parallel ?

- Pure on-grid condition: up to 50 units in parallel
- On & Off-grid condition (UPS): up to 2 units in parallel

Is isolation transformer required ?

Isolation transformer is not required for this product

Are there any on‑site requirements for the installation of STORION-LC-TB125 ?

If the ground at the installation site is uneven or there is a risk of standing water, it is recommended that a foundation be installed.The outlet of the StORION-LC-TB125 is 
located underneath the cabinet, so it is recommended that the foundation be constructed with a pre-drilled wireway.

What are the battery storage requirements ？
