SERVICE FAQ

Frequently asked questions about our engineering support.

Practical answers on commissioning support, warranty cases, and storage additions.

Who do we call when a question comes up during commissioning?

Our engineering desk answers startup questions by phone while your crew is on site. When an inverter or battery reports an error during commissioning, our engineers work through the fault with your technician: the error log, the communication settings, and the steps back to normal operation.

If a component fails, do we deal with Linker or with the manufacturer?

With Linker. Equipment supplied through us stays our case from the first fault report to the replacement. Our engineers review the failure with your team, open the claim with the manufacturer, and coordinate the replacement. The manufacturer conversation stays with us.

How is a storage addition planned for an existing PV system?

Storage additions start from the installation that is already running: the installed inverter, how the site consumes power, and where the metering sits. The Solution Configurator sizes the battery from that installation, and the compatibility lists on file show which batteries are listed for the installed inverter. Check the connection parts before anything is ordered.

Can a storage system be expanded after it has been running for a while?

Yes, if the addition matches the installed system. New battery modules have to match the voltages, the firmware, and the condition of the stacks already in operation. Check the expansion rules in the product documents before you order the addition.
