A South African installer (QAL Greens) reached out via Facebook after their Ingeteam inverter and Pylontech battery wouldn't communicate. 100up's working-install knowledge filled the gap that local support and official documentation couldn't — a battery-side firmware update resolved it.
Sometimes, off grid solar installers end up helping each other from opposite sides of the world. This one started with a message on Facebook from an installer in South Africa who was stuck on a system using an Ingeteam inverter and Pylontech batteries.
The local team on the ground had run into a wall. The pairing was new, the system would not cooperate, and local support channels did not have the answers. Instead of guessing, they tracked down a working install and reached out directly.
QAL Greens is a renewable energy resource company based in South Africa, specialising in the design, construction, and management of sustainable energy systems. Their work covers solar PV, solar water heating, and water harvesting, with a strong focus on practical, site-specific delivery across residential and commercial projects.
It is a good example of how real world install experience travels faster than official documentation when new system combinations hit the ground.
The issue centred on a newly supported inverter and battery pairing that required a firmware level update on the battery side.
This is a common failure point in hybrid and off grid systems where integrations evolve faster than support frameworks.
With access to the correct files and prior experience, the issue was resolved remotely.
The key takeaway is not just that the system was fixed, but that working installations become proof points others rely on when official channels fall short.
