I am beginning to believe my Tempest is cursed. Power Booster will not work correctly, whether a field test model, or official PB release.
A ticket is open so I am hopeful. At the same time my overall experience with the Power Booster using batteries, is it charges my Tempest all the time. Or not quite all the time, Every once in a while it stops charging for a bit. Have been mostly above 2.6 volt.
I do not know what percentage of Tempest/Power Booster still have the problem. Wishing the team good luck chasing this problem to ground.
Iâm waiting for mine to drop below 2.6V (above this Voltage it just constantly charges) to test the charging cycle on the new firmware but have read conflicting facts as to how the power is applied with the PBA.
NO BATTERIES ONLY MAINS POWER with my PBA
So when the PBA is is powered on AC/DC upto the point of full charge and then itâs unplugged, Tempest will discharge until the V drops below 2.7V then it will charge via the solar panels (with fw 165) @gizmoev Youâre device must be diffâ as I waited until the Vâ was below 2.6V and then plugged in the PBA and it carries on charging indefinitely up to 2.8V and keeps it there until it is unplugged and cycles as I have described here
Are you seeing trees late to leaf out? I am seeing enough solar radiation to charge my Tempest way past previous dates. But right now my Tempest is not charging. The replacement PB seems to be ok right now, except support cannot see that the PB is attached to the Tempest. I have had the darndest luck with the PB. But I remain optimistic.
Silver maples starting to leaf-out (lateâbecause of GCC . . . Global Climate Change.) Lots of trees in the area were trimmed back (contractors for the local power company). All 3 Tempest devices have managed to reach optimum battery performance levels for past month or so. Havenât had to use the Power Booster since like back in late March. . .and that was only temporary due to several days of cloudiness. One Tempest device had a battery charge controller fail. . . wouldnât charge up where by âel Solâ OR on Power Booster. So I ended up sending it back to Daytona Beach for Repair. I chose to pay the $30 repair fee instead of having them replace it and sending me another one. Wanted to keep the integrity of that device because I was sentimentally attached to it! Days here lately have been âa mix of cloud and sunâ but even with the clouds all 3 devices manage to reach at least 2.80v all on their own every day now! Leaves not so much of a problem this year because trees got a decent âhaircutâ (thinned-out) so thatâs no longer an issue.
My Tempest battery is pretty close to flat-lined for quite a few days despite good sun. Sits there somewhere between 2.6v and 2.56v. I have never seen that happen before. It is almost like the PB is providing a trickle charge, which I am sure it is not.
The foliage has finally asserted itself. I am dependent on the Power Booster now. Fortunately I was sent a new PB and it appears to be working for me. When voltage dropped to 2.42v the PB charged the Tempest battery to 2.6v.
This is the first time I have not seen full-time charging from one of my PBs. Iâve managed to regain a bit of optimism.
Anyone have an idea how many charging cycles to expect from a set of 8 Ultimate Lithium batteries?
For several weeks I have been back to charging full-time.
After 8 or 9 charging cycles I began to see the normal cycle of charge and discharge begin to deviate and eventually settled on maintaining a 2.77 volt, âfull charge.â
Ha! I have heavy foliage in the summer, so no way to keep the Tempest charged via sunlight. My production PB (on batteries) always keeps my Tempest at 2.77-2.78. It never seems to shut off like the docs say it should. I had opened a ticket and support replaced it. Same behavior, so they replaced the Tempest. Same behavior. They wanted to talk to engineering about next steps and that they would get back to me. That was in early July. I think their design is flawed, but what do I know?
I finally got around to installing my power booster - it hasnât been needed yet. My Tempest (Station 43067) is still on FW 156 though, is WF still pushing the updates automatically when the booster is detected?
However since connection Iâve noticed the battery voltage dropping and itâs a moderately sunny day. Iâm guessing this will be fixed with the FW?
Hi, I saw that if you have firmware revision 156 the booster wonât work, so I am commenting here to request the update to my tempest. I am on power reserve currently, and this time of year my solar panels basically stop functioning. Thank you.
It has been attached for two days now. Support said theyâd forward it to a tech on Monday, and to power cycle the unit using the switch on the bottom. I have done so, and no change. So I suppose Iâll hear from them on Monday.
I have been using PBA with AC adapter (240V) since December 5
for the first 5 days the PBA kept the Tempest voltage at a constant 2.81V, behaving exactly as described here
from about 9th December the battery level in Tempest started to fluctuate between 2.72-2.81V, it was very sunny days when my second Tempest (without PBA) was well charged
since about 11 December the Tempest always recharges to 2.81V and then discharges for 2-3 days to about 2.6V and recharges again to 2.81V
now for example the Tempest voltage is 2.59V and even though the PBA is connected the Tempest is not charging
please note that all the time the PBA is connected and powered from the original mains adapter (240V)
the station firmware is version 1.56, Tempest ID 52673
