Eventually... we have fully operating system! Thank you Gosolr.

Gosolr's after sales service was not good at all. Eventually, after 20 days of calling in daily after the battery failed 30 minutes into each loadshedding - a team was dispatched to investigate. This is, only after I demanded they come and deinstall the solution as it wasn't delivering the expected / advertised objectives. They discovered the geyser was connected to the inverter and resolved the issue in less an 30 minutes. It took countless calls and emails to the Gosolr team that just tinkered with the battery settings remotely and insisted that nothing was wrong. All I had asked for was the installers come onsite to check for install issues.

Finally, on day 23 we have lasted through a full 3 hour loadshedding without battery failure. Thank you to Gosolr and mostly Tasneen for going the extra mile and escalating my case.
