Support has been helpful. My biggest issue is that I would like the app to have an option to connect to the unit so it can give you live data. There have been a few times that the cloud has been slow and my data takes a while to update.
I have the 10kWh battery, and the whole home gateway. Many times the power has gone out and I did not even notice.
Reclaim 10-30% of the power you don't know you're losing.
I knew I had a couple of shaded panel, because we have about 600 trees on our 5 acres, and our neighbor's property is at least as tree-dense as ours. My greenhouse array of 20 Waaree 590W panels (arranged in stacked portrait layout) is surrounded in a canopy, but only one tree is right at the array. The rest are ranging from 50' away to over 100' away, but I didn't realize just how shaded certain panels of the array were, until I put TS4-A-O optimizers on a few panels at a time.
My array is a 5S2P configuration, so 4 strings of 5, in 2 paralleled MPPTs. MPPT1 has always "seemed" unshaded, but we're about to find out for sure.
MPPT2 I've always known had "some" shade, but I never knew just how bad it was, until all 10 panels of MPPT2 had optimizers, and I could see each individual panel throughout the sun arc of the day. The lower set of 5 barely making anything until 10+AM, and now when I look back at the historical data, before I had optimizers, it makes sense.
How do TS4-A-O's benefit you?
1) total module-level visibility.
2) enabling rapid shutdown.
3) reclaim every watt of power feasible from your array.
I've seen as low as 13% reclaimed and as high as 30%, but if you have mismatched panels, it could be more. My ROI is about 14-20 months on just the cost of the optimizers + the CCA logger. Definitely worth it, in my opinion.
And you can integrate Tigo EI with Home Assistant or your EG4 monitor app.
They do need to work on the ease of installation. There are plenty of videos you can watch, but until you go through the commissioning process yourself, you won't understand exactly why it's not as intuitive as it could be. Some things are just done out of order. Some things need to be done through the "view" screens, that should be feasible through the "edit" screen flow. But, I have zero complaints about quality or capabilities. Excellent product, and I'll use them on all my array builds.
Great technical support and working great. Software interface can be buggy but has improved.
Everything worked great out of the box. Install videos and documentation were comprehensive, although some models differ slightly making some decisions confusing (eg how the inverter integrates with the ATS). Everything just works otherwise. I do wish it had an external display so that I could have a better idea of what was happening outside of using the app.
