Anybody have low voltage problems with the Solix?

We have constant low voltage alarms with the Solix 10. We replaced the starting battery, and 3 bank battery charger just in case that was the problem. A couple months ago we bought a Solix for the console, and it constantly had low voltage alarms, even though it was fully charged. As soon as you put something else on (live well, etc) the alarm would start. Now we have one up front too and the same thing is happening. We don't even have anything else on at the same time and it happens. We could never use both of them at the same time. It happens even when nothing else is on too. Fully charged, still happens.

Any ideas as to why this is happening? Do you have to be moving when using it? Thanks.

I am not the owner of a Solix, so I am just guessing!!!!!!!

Is there a setting for the voltage readout??????
This may have to be reset to a lower voltage, example 10.5V...:twocents

I have had a Solix 12” since they first came out.
No problems with low voltage.
Call HB they have great customer service!!
I do think you can adjust the voltage alarm, but don’t remember how.
I think the wiring could be to small..... maybe Rickie or one of the other guys will chime in.

It is recommended to install dedicated fused wiring from battery to unit ... and not use boat harness wiring, (which is usually too small with too many connections that can cause voltage drop across the entire circuit) ...

HB recommends 14gauge - 12gauge is better - I use 6gauge to a fuse block and then 10gauge to each unit ...

There's just not that much difference in cost of increased Gauge wire for peace of mind ...

Some opt for a blade type fuse block like below if there are more than 1 unit to be utilized ...https://www.bluesea.com/products/cat...locks/ST_Blade

In either scenario - the wire circuit must be protected by fuse or circuit breaker as close to the battery as possible (according to ABYC standards https://abycinc.org/general/custom.a...=StandardsList)

The above is all good advise. As Redge said you can set the low voltage alarm on the hummingbird in the settings. I've got mine set where if it goes off I know I need to start my big motor and make a run to charge the battery. Also just because it s a new battery doesn't mean it a good battery. Have a load test done on it and make sure it will hold a load. There are a lot of new batteries that are not good batteries. My 998 does the same thing with a optima yellow top battery but I know I have a bad cell. It will start the boat and does fine tell I turn on SI/sonar on the 998 without the big motor running. I've talked to a lot of people that are going to a separate battery for their sonar to prevent voltage drop and to protect the sonar units and also help reduce with RF interference. Electricity is always a mystery, good luck and let us know what you find out.

Had that same problem with my old setup.Now have 2 Helix 10's ran 10g circuits for each unit straight to battery problem solved.

If your actually experimcing a low voltage problem that's causing units to shut down follow Rickies post and others on wiring and size. If your just getting a low voltage alarm or warning, go in to menu twice, go to alarm, scroll down to voltage alarm and set it to 10.5 volts. That should be low enough to keep it from alarming but still give you plenty of voltage to crank motor .

One more note, all my FF and HB equipment is on a single dedicated battery, nothing else on the circuit.
Solix 12”, 1198, 360, Ethernet switch, nema 2000 is also on that circuit.

Thank you very much. Will try upping the wire size first. Will report back to see if that works!

I wish we had room for another battery, everything is on the starting battery. We have two other batteries for trolling matter and out of room.

Thanks. The units are not shutting down, just the alarms. The default is already set at 10.5 now .. and that's what the alarm says when it goes off .. within a very short period of time. Looks like Humminbird allows voltage alarm to go to 10 at lowest. You can turn the alarm off, but don't want to do that.. want to figure out how to fix it. I'm going to try some of the things here .. just wish I had room for another battery too!

Thanks. Will post back when have tried some of the things mentioned. The low voltage alarm is already set at 10.5, 10 being the lowest setting by HB. New battery would help probably, but no room. Will change wire size first and see how that does ..

Thanks. It's already set to 10.5 .. seems only to have 10 being lowest option.

First question I have to ask is, what is your voltage at the battery and what is the voltage at the unit(s)? Battery should be 12.4 to 12.6 volts on a charged battery with surface charge removed. Units should be within a few tens of that. Should have a system screen on unit that gives you voltage the unit is seeing. Had similar problem on my Helix 12. !2.4 volts at battery but 11.6v at unit. That indicates a voltage drop due to high resistance. Turned out to be inline fuse holder. Removed fuse holder and went straight to fuse block. No more issues.

Thanks ... yep the battery was 12.5 and the unit was 11.1 so definite line loss. We don't have fuse holder, but going to change wire size today to see if that helps ..
PS See you're Dan's Jigs... I'm Dan also .. make jigs too. :)
