You did not say what kind of problems?

Are you running the Venus image or separate packages?

is the multi /bluesolar updated to latest firmware? if not you will need a windows computer to do so

A great resource for raspberry pi troubleshooting is the developer moderated googlegroup of venus

On top of what Oga BigRovar has said, may I also add that if you use the battery in this way, discharging it all the way to the end, it will surely die a early death.

A 12v 200Ah battery at the top of it's game has about 2.4kWH of energy stored in it - a 200watts discharge is effectively C12 and you want a C20 discharge rate so as not to stress your average battery - by C20, I mean a discharge rate or load that will need to run for at least 20hours before your battery is fully spent.

So for this scenario, ideally you want to either drop your load to 100w and run this for 12 hours to get your battery to 50% DoD or add one more battery to make 2 units of 12v 200Ah then you can safely run your 200watt load for 12hours and comply with both the max load and depth of discharge rules and thereby secure best service life for your battery bank.

To acess venus you have to be another computer and point your browser to the Ip address of the venus. The VRM screen is available on remote PC and not the pi

what voltage 6V 12V 24 or 48 V? 200AH at 12 V is 2400 Watt hours. Usable is half of that which is 1200 watts hours. Divide you 200 into 1200 and you have your answer.

Hello,

We can only place orders on amazon USA for now.

Thank you.

Thanks dear, this is really helpful.

What could be the wattage of an average 1kw inverter?

bigrovar:

Try what oga pranil posted or wait for a new venus image that supports the Rpi+. The issue is the venus uses an old boot loader which is not compatible with new hardware included in the new Pi particularly network drivers. Pranil linked post gives a work around the problem but might be better to wait. The venus community are very active and a new image should be released very very soon.

I was tempted to use VRM too for remote logging and monitoring what held be back was the proprietariness of the VRM service (not venus) in the end I settled for emonpi with emoncms. That gave me greater control over every aspect of logging and monitoring. You can see my dashboard in my signature.

i will sure love to give them a try but quite frankly, haven't done any remote system all myself but very familiar with linux commands and its queries .... but will be happy to be thought.

Hi, pranil;

I must say the ease and frequency at which you and others throw in useful resources on here - and also explain them - is both inspiring and helpful to yours truly.

i noticed that you have only just one Quattro which i believe is a single phase and that being able to handle a few things ...
plus if the generator is 20KVA then you can simply go using 2 more quattro and one as the master and other slave .... with a maybe a pheonix victron to be strictly for critical et cetera.


plus have worked with fronius 25/27 Eco series three phase and i will say that you have the system properly setup ..... well done.

Sorry I mean the idle wattage or maybe the current it draws/consumes from the battery

cc bigrovar

thank you for this simple analysis, a little new to all this, so have a 5kva 48v inverter with 4 x 12v x 200ah, and 2kw solar panels, now the installer said i could run 2hp ac, or even my 1.5hp sumo, or a 2kw pressing iron for a few hours if i want,have been doing this for a few months now, no issues, but your explanation about c/10 and c20, its clear to me that i may be over stressing my bank.

now am thinking of adding another 4 x 12v x 200ah batts to my setup to lessen the effect of running such loads. my question is, is this a good move?..mixing a 2months old stressed bank with new batts?. how do i know if the old bank has been damaged, thus increasing the bank, wouldnot do anything?

Brevir:
Hello house, please, what are the optimum charging parameters for charging 4 number 12V/200AH batteries.
The set up seems to be doing fine, but charging parameters is currently set to user defined, with bulk charging voltage=58.8
Float voltage= 56.4
Total charging amperes=60A
Utility charging amps= 30A

I'm I better off leaving them this way or should I revert to the preset charging setting for AGM battery?

I don't want to have any issues with batteries in the future

Inverter Brand: 4KW ipower plus
Solar capacity: 3KW
Battery brand: Kung Long

NiyiOmoIyunade:
Hmmmmm my Oga

Except you are running all these loads when there is power from PHCN or Gen then I fear for the installer who said you can run a 2hp AC for a few hours off just ~10kW of lead acid batteries o!

Even with 8 batteries it would be a stretch because you will have other loads still running at thesame time.

With 2kw of panels and 4 12v 200ah batteries you should only be thinking of basic loads and perhaps 30 mins max with the iron or pumping machine - running a 2HP AC should not come into the picture when there is no mains power available except your batteries are in Float and the PV array can keep them in Float with the AC running [will be a tall order for a 2KW array with a 2HP AC]

If your current battery bank is over 3 months old I would not recommend adding a new set to join the old. Even at two months, care needs to be taken to when combining old and new batteries - they have to have very closely matched capacity and state of charge.

I think you need to sit down and evaluate what your power needs really are and this will help guide what manner of upgrades (if any) you need to perform. Except you have a fat budget you should prioritize your loads and only size up for loads that you will run regularly.

NiyiOmoIyunade:
Please see the KungLong battery spec sheet below;

A float voltage of 56.4v is 14.1v per 12v battery, this will certainly kill your battery in the long run - max float voltage should be 55.2v or 13.8v per 12v battery.

Your Absorb voltage is fine per the spec sheet but for an AGM type battery I would be OKAY at between 14.4v to 14.6v max per 12v battery - ESPECIALLY if you don't have TEMPERATURE COMPENSATION on your charge source and I dont remember seeing that bundled with the IpowerPlus I have seen.

Also is there a reason you chose to restrict your utility charging amps to 30a? The IPowerPlus can go up to 60a and possibly 80a (newer models) for utility charging - your AGM batteries should be able to take 40a to 60a with ease.

To be safe, a user should not fiddle with user defined settings unless you specifically know what you are changing and why you are changing it as well as the consequences.

You are highly welcome! See snapshot below for our Vietnamese kung long battery charge settings . Feel free to reach me for further enquiry . Cheer's !

NB: multiply whatever volt(per cell) you see ×6 to give you 12v readings !

many thanks.

this guy is a fraud..no 2 way about it. he can't even produce receipts and has stopped responding to my messages

am almost sure he installed refurbished or fake items.

last we spoke b4 he stopped responding...he's telling me he can't return the batteries as they gave him only 2 wks to return.. batteries that are not even yet 6 months old as of today july 25 and they failed completely since late may

he's a fraudster

his name is john....no is 07069331631

has a jiji page that he uses to scam ppl
