Home Battery Storage & Complete Power Management

2

This is a depiction of a typical home battery / PV system installed. There cost of permitting, design, rewiring, and installation can exceed the battery cost by several times.

The Challenge

3

The inverters and chargers have little autonomous control or management and there is very little data insight on performance causing electrical network and grid instability. They are also vulnerable to internal or external grid fluctuations.

3 3

Typical efficiency does not exceed 80% and requires

additional cooling to prevent from overheating

The Challenge

4

The Challenge Electrical networks must be rewired and additional subpanels must be installed to separate the critical loads decreasing network control and stability

Why this matters? Every single existing home battery system on the market today reduces control over the electrical network by integrating many complex devices from different vendors in a new electrical network wired by a local contractor.

“… voltage fluctuation is severe and may exceed the limitation. The inverters … will turn down to protect themselves. This hastens the [grid] toward go into blackout. Therefore, it is not easy for a [grid] to provide uninterrupted power supply during the transition from grid-connected to islanding operation. ”
