It’s a great feeling when stuff starts workingThe fan at the back of the ali? Rids is genius....
I'm actually in a similar place but without much wisdom leecy wise to gratify that. I started the day plumbing stuff in and spent most of the day updating........my web is pitiful in the sticks. Much to my amazement most of it works.my cut off failsafe to B2B switch works Del's temps sensing relay works , me fan pulled the temp down of the Orion while it was pulling 32A and held it . It was a brief test like yours Rids but really promising I'll need to dig at this much deeper .but for a first day it's promising at least
I think I need a diode one in one out say 30A max any help please lads?
thank you
Cutting out the 140mm diameter hole in the 5mm plate was not the work of a moment…The fan at the back of the ali? Rids is genius....

Where/why do you think you need the diodes?The fan at the back of the ali? Rids is genius....

I'm loving the the 2.41 firmware update on the mppts.
Where it shows stats on the front page.....

I started with a brand new hole saw; which was a battle… then I thought it doesn’t look big enough a quick check on the box revealed 114mm not the 140 I thought I’d bought… number dyslexia is a thing!@Rids
reply 1 ha ha yes but today it didn't want to play.unsure on cause.but spent a goodly while thinking I'd broke MPPT......I noted the BMV 712 was not showing a numver inside the circular first page on phone...when somehow that started working so did the MPPT....think BMV was telling MPPT battery full so MPPT wouldn't charge ......I'd discontected battery overnight so maybe this was part of the cause.mind me and the digital world always seems to be a knife fight..... got there all working again but as ya say not the work of a moment
2 Ha yes I get that wow 5MM...what tools used? Jigsaw? Hmm ya do realize there's a whole generation of us that grew up wiith Blue peter and think anything is possible with tape scissors an a bit of plastic sheet?
3 I want to try and use the MPPT's (75/15) load output ( and vic's batterylife algorythm) to charge the starter battery............not the convention I know most would use something like an Ablemail trickle charger but I've been told it can be done.so want to try and explore that to see if it's possible..................
I need to block current coming back from the starter battery into the load output so figured a diode might be a way of doing that? The 30A is a figure pulled from the ether...I tend to do overkill... from what I've learnt so far the amp figure might me much much smaller.I monitored around 3amps yesterday
There might be another more appropriate way to achieve that block on the flow of electrons but I'm learning so ask the stupid questions......they give me something to run with
The photo was taken after the batteries had recovered. It was in absorption mode when I considered the thing incapable of waking up the batteries.Possibly a bit too impatient.
The pic shows the Ip65 in bulk mode indicating that it's was delivery a good voltage and current.
Not sure on the TN Power spec about waking up....
But two 100ah batteries will take a while to take enough charge to wake-up.

Ah that'll be me being impatient then! Thanks for this.Most lifepo4 just rely on a voltage above the set point to wake them up.
Ie. 14.2v, the battery will draw a very low current as the cells start to rise in voltage to the point the BMS wakes up.
It depends on the battery as to how long it takes.
As an example the last Renogy 100ah I don't it on took 2 hours to wake.
Hello! thank you for sharing this, I have put it to good use.Exactly but that is ok for me, as there is 400w of solar too, so the last few percent of battery charge should get there in the end unless the DC-DC stops giving the 300w I need to run. If it does then the water heater will switch off when battery depletes to say 95%.
BTW- Re your comment about the solar backing off when battery is full; You could pretty much do that already. You could do this by tricking the GX device into thinking it has a genset, but simply use the "conditions" to switch a load off or on to suit your requirements.
Here is how.
In the Remote Console on the Cerbo GX or Venus GX, go to settings and change the relay use as "Generator start/stop":

Next go settings-generator start stop:

Make sure auto start is enabled:

Then go to settings-conditions to set the conditions. So that the "genset" turns off at 100% charge and on when the battery is depleted to say 95%. (This is more reliable than using voltage as the trigger, because the load will cause a voltage dip and create problems if you don't use battery %.)

If you wanted, you could set up quiet hours and so the water only heats in a morning, leaving the afternoon sun to leave you batteries at a minimum 99% at sundown.
The above settings will trigger relay 1 on the GX device according to the conditions that you set.
The N/C relay port needs to be used, as the idea is that when the "genset is running", whatever big load you are powering is off.
IE- Genset start=load off
You can take this GX relay to switch whatever you like. (Via a heavy duty relay of a suitable size.)
