I recently connected a 24v 5a power supply to a 40a mppt and the power supply voltage kept getting pulled down to ZERO. But in another instance, I used to connect an 18v 1.5a supply to the mppt input on my vehicles dc-dc charger while it was parked in the garage to keep the batteries maintained and it worked perfectly.
Yeahh that''s the idea! It''s supposed to send power downstream when solar is working. And when it''s not, the automation shuts down the power transformer and sending power the other way around (from base to space). The thing is my smarts never got charged by solar, so my power downstream gets sucked to space while my solar panels keep overproducing.
I was under the impression that if the solar panel ran out of power, the Ring App would show it as disconnected. Also, if the solar panel is not out of power, it should start charging the battery automatically once it drops to 90% or below. According to the symbol shown in the Ring App, the solar panel is connected but not charging the battery.
Recently I got a UPS (uninterruptible power supply) from a Big server tower. It is possible to connect a UPS to a solar system, but it requires some technical knowledge and wiring skills.
