Battery Communication: Closed vs. Open-Loop Communications

Open-loop communication is what we commonly see in systems with lead-acid batteries. In this setup, the inverter uses tools, such as a shunt, to estimate the battery''s state of charge (SOC) from an external perspective by measuring the change in voltage as the battery charges and discharges as well as the amount of current that has passed into or out of the

Lithium Series, Parallel and Series and Parallel

Connecting batteries in series incrementally adds the voltage and stored energy potential of each battery connected in the series string without changing the total amp-hour capacity of the completed battery bank.

6 FAQs about [Battery and inverter communication design]

How does a battery-inverter system work?

In a power system with closed-loop communication, the inverter, solar charge controllers, and other components do not control the battery. Instead, the battery informs the decisions made by everything else in the system. The performance of any battery-inverter combination depends on how effectively the battery can fulfill this role.

What makes a good battery-inverter combination?

The performance of any battery-inverter combination depends on how effectively the battery can fulfill this role. For the battery to receive what it needs and for the system to operate at peak performance, these control messages must be accurate and well-understood by the rest of the system. As you will see, this is not always a given.

What is a basic battery communication system?

In a basic battery communication system, the main information shared is the battery telling the inverter whether or not it will accept or give a current at this moment. A system with basic communication offers reliability and noticeable performance advantages over non-communicating lithium batteries.

How does a hybrid inverter work?

The efficient operation of a hybrid inverter relies heavily on seamless communication with lithium batteries. Properly establishing this communication ensures that your energy storage system performs optimally, maximizes battery life, and maintains system reliability.

How do you connect a lithium battery to an inverter?

BMS Communication Link: Most lithium batteries come with a built-in BMS that can communicate with the inverter. Ensure that this link is properly established by connecting the BMS output to the corresponding input on the inverter.

Are budget battery companies compatible with inverters?

Most budget battery companies don’t have support from the inverter companies they claim compatibility with. Rather, they reverse-engineer communication protocols established by officially supported brands or simply buy and incorporate their BMS boards.
