Yes, we can install battery storage alongside a system that we have not installed. This is classed as a retrofit installation. We can give you a price for a system size but will need to conduct a site survey to make sure your system is compatible with the battery storage you have chosen.

The depth of discharge is expressed as a percentage and is the rate that a fully charged battery can be used before it has to be recharged again.

For example, the lithium ion batteries we install have a maximum depth of discharge of 80 %. This means that the batteries can be used until they reach 20 % charge, and then will not discharge any more power during this cycle.

Once the battery has reached down to 20%, it will then start to charge back up to 100 %.

The depth of discharge is set to 80 % as this helps preserve the lifespan and health of the batteries installed.
