Power Booster working continuously

I plugged in my booster with 8 AA batteries when the internal battery dropped below 2.4volts. The system then charged up to 2.77volts, however it has stayed at that level continuously for three days. This suggests the booster is permanently powering the Tempest and depleting my external batteries. I didn’t think it was supposed to do this. Does my booster have a fault?

IIRC, it is the Tempest which determines when the booster charges but maybe the booster isn’t notifying the Tempest it is on battery power rather than external power. The firmware on your Tempest is v165 which has the smarts to know about battery vs. external power.

Maybe @eric can have a look behind the scenes at what may be the issue.

The Tempest is on FW165 so that is good. From what I see you have taken the bosster out.

Try again but reboot the Tempest before via the switch underneath and let it boot (wait 1 minute) once that done, re attach the wafer and the rest of the booster.

Let me know when it is back linked and I’ll have another look.

Thanks Eric. I haven’t taken the booster out. It’s still connected and the Tempest is still showing 2.77v. It’s a little difficult to get to, so I’ll need to wait for daylight tomorrow. I’ll get back to you after I’ve reset it.

I had the same problem. Eventually we replaced both the tempest and the booster. As it turned out… it was the booster causing the problem.

When I was field testing, I had to manually charge a Tempest to get it running again. Since this was done with just a power supply, no logic was involved. I wonder if the Tempest not able to communicate with the booster is why some Tempests stay fully charged when the booster is on batteries.

Hi Eric. The Tempest is now reset, and the booster is connected.

Just had a look, you have plenty of sun and the Tempest charges with that though it does not see the booster. It did in the past so something in all the linking must have gone wrong. Or the batteries are depleted (or maybe just one causing the full set to fail ?? Measured with a meter ?)

I think the readings are misleading. There’s been no significant sun on the Tempest today (maximum solar radiation was 142 w/m2 for a short period). I think the external batteries have taken the voltage back up to 2.77. It’s been dark for an hour or so, but that voltage remains constant. There must be a communication fault between the two devices.

My Tempest continues to draw its power all the time from the batteries in the booster. There must be a fault in the communication between the devices. My booster is still under warranty; how do I arrange for a replacement unit?

Open a support ticket with the link in the menu above. Include a link to this thread so you don’t have to repeat everything.

Thanks David. I’ve done that.
