Not all battery inverters are equal

With the installation of energy storage systems most people look at the battery and concentrate on that but in reality the battery inverter is an integral part of any energy storage system and will dictate much of the energy storage systems operations.

Often when an energy storage system isn’t working properly the fault lies with the inverter and not the battery.

Inverter power is measured in kVA or volt amps.

The battery inverter takes power from the solar PV array (solar inverter or MPPT) and battery which can be of different voltages and converts it to 240V for household of business use.

Solar inverters are designed to work with solar PV arrays and battery inverters are designed to work with energy storage batteries. Hybrid inverters are also coming onto the market that combine both solar PV and battery conversions.

SoNick battery BMS or Battery Management System

Some Energy storage batteries have a built-in BMS or Battery Management or Monitoring System to monitor how a battery operates and how it talks to the grid. This is an electronic system that manages a batteries function by protecting the battery from operating outside its “Safe Operating Area” both for the batteries health and to prevent any accidents that the battery could cause by malfunctioning.

The internal BMS monitors and controls all charging and safety aspects of the battery. The BMS will also keep you informed of the state of the battery so you can monitor the batteries health.

When integrated with other SoNick batteries the SoNick BMS synchronises the operation of the battery bank so that all batteries work together as one large battery.

Are batteries guilty as charged?

Very interesting article from Ecogeneration based on CSIRO report that raises many of the questions about the lack of standards in the battery storage industry that we have been talking about. The lack of standards, particularly around fire risks of lithium ion batteries means safety can become a serious issue. It is definitely an issue that needs to be addressed as soon as possible.

CPat---Power-security

 

For many people the need to protect themselves from power outages is becoming a more and more common occurrence and it is not unusual for it to take days for the power to be reconnected, particularly if you are not on a main line and other lines take priority.

 

Sometimes people lose power due to storm damage to power lines but often it is power being cut off by power companies so that they can do maintenance on the lines.
