Solar Boost reads "01" amp/hr when batt is fully charged---a problem?

August 20, 2016, 06:21:32 pm

Hello Technical Gurus,

In running through the displays on the face of the Blue Sky Solar Boost 3000i, I noticed that the amp/hr display read "01".   The display indicator on the solar boost was lighted at "float" and 13.2 v.  Normally that amp/hr reading is close to 200.   Does this mean my batteries are not holding a charge?

Further information:
--I was running the generator with AC on during the reading.  (Prepping the rig for Ladeze in a couple of weeks).
--The Victron meter "history" says that a deep discharge occurred to 10.4v (this message has been there since the install several months ago).  Is this low enough to ruin the batteries?
--The battery needed to be refilled with a lot of water (maybe 2-3 cups?--a lot of squeezes on the battery filler).  The low water in the battery occurred a couple of months ago.
--I had Vince install a house battery disconnect, as there seems to be a draw of about 0.9 when everything inside the rig is off, including the dash radio.

I am getting the T-105s load-tested tomorrow.

Any words of advice for me before I get the batts load-tested?  I like to be prepared before heading to a repair shop.

Thanks in advance.

Thank you so much for your reply, Steve.

Would I normally find the fuse to the charge controller in the battery box?  If I am getting a load-test tomorrow on the house batteries, will they have to disconnect the batteries from the system to do the load test?  If the answer is yes, then I will need to find that fuse.  I do know where the fuse is to the LD-installed solar panels, if that helps at all.

Thank you for your response.

Thank you all for your replies.

Because of the water usage in the batteries and the deep discharge message on the Victron a few months ago, I was concerned that the batteries might have been ruined.  When I saw the "01" on the amp-hrs on the solar boost, I kind of over-reacted.  Thank you Steve for reminding me that the solar boost amp-hr reading is the solar delivered since the last re-set.

  The warnings about removing the fuses prior to disconnecting the batteries has me a bit concerned.  As I mentioned in my original post, I had Vince add the battery disconnect to the house batteries so there would not be another "deep discharge" during (indoor) storage.  The battery disconnect when in the "off" position also causes the Victron and solar boost displays to go dark.  Would I need to remove the solar fuses prior to each time that I move the house battery disconnect to the "off" position?  Am I over-thinking this?

The nice gentleman who performed the load test today was able to access the batteries with the slide out tray extended so he did not have to disconnect the batteries (Whew!). He connected the load tester to both batteries in series and used the 12 volt reading on the tester.  He said the batteries were fine.

Now, on to prepping for the trip to Idaho to meet the Ladeze!
