Zendure Satellite Monitor CT – Smart Home Energy Monitor with CT Clamp for SolarFlow Power Adjustment

Before this, my SolarFlow system just exported blindly. With the CT clamp it reads house consumption and adjusts output in real time — no more pushing power back to the grid. Installation was a little intimidating around the breaker panel, but the instructions were clear. Per-watt adjustment is smooth, no flickering.

The monitoring accuracy is impressive and the app graphs are genuinely useful. I'm comfortable with electrical work but would tell beginners to get an electrician — you're clamping around mains conductors. Took 30 minutes total and it's been reliable since.

If you have SolarFlow, just buy this.

The power adjustment feature is exactly what I wanted and it does work. But initial pairing with my WiFi took several attempts and the firmware update failed once mid-way. It's been stable for a month now, so fingers crossed. Good product, rocky start.

Had my electrician install the CT clamp during a routine panel service — five minutes of his time. Now the whole system balances itself: when the dryer kicks on, solar output to the battery drops automatically. My usage graphs let me spot that our old fridge was drawing way more than it should. Paid for itself already in insight alone.

Compared readings against my utility meter over a week and it's within about 1-2%. Zero-drop feature works as advertised so we never export when we don't want to. Cable could be a little longer for some panel layouts, but mine reached fine.

I'm 70 and not great with apps, but my grandson set this up in one visit and now I just glance at the app to see everything. The house draw versus solar chart is easy to read. It quietly does its job and my bill went down because the system stopped exporting power we needed.

Accuracy seems fine when connected, but mine loses connection to the hub a few times a week and the power adjustment stops until it reconnects. Tried different outlet, re-paired, updated firmware. Support is responsive but hasn't solved it yet. Expected better.

I delayed buying this for months thinking it was optional. It's not — it's the brain of the whole setup. Real-time load matching means our 4000 system now covers far more of our evening usage because nothing gets wasted. The install manual even had clear photos for different breaker types. Absolutely essential.
