I am not planning to use solar now just inverter and tubular batteries and from your submission is better to stick to the icellpower 2kva inverter and then buy a charge controller when i upgrade to solar rather than use the axpert 2kva hybrid inverter which is more expensive and still buy a charge controller when i want to upgrade

Please confirm if your icellpower 2kva inverter is not an Axpert inverter branded as icellpower. Alot of companies brand Axpert with their own names but in reality it is still an Axpert.

Take a picture of the inverter our learned gurus will be able to tell you if it is a branded Axpert.

Victron 5kw x 3 to make 3 Phase Power + Additional Fronius 6kw in 3 Phase e.t c

What shall one say to these things? You are afterall both master and enthusiast all rolled into one

When are we going to get a review of your new system? (this one don pass upgrade o). It has to be done with full aplomb and fan fare.

And also are you planning to sell off the Axperts and DC generator you already have?

For your diesel gen, I thought you already had a small solar panel connected to top off the starter battery? I see no reason why you do not simply 'strike' the Gen - either leave it idle or just drain fuel out and set it up for long term storage! I do not see how you can have a blackout with all the PV capacity and multiple inverters and multiple redundant battery banks you have built up and it does seem running the Gen occasionally is more trouble for you than it is worth (surely the houseowner would have no objection to prepping the Gen up for long term storage?)

pranil:


I second that.

Apart from SMA, I have not come across a company so knowledgeable and helpful on different application scenarios and wide har4dware compatibility

There is no comparison to their open source approach in the RE business

I have put so much faith now in Victron that I pulled out my entire system and in the process upgrading to 5 KW Quattro x 3 phase setup .

The generator and NEPA will changeover through Victron so something goes wrong my house will be in darkness

I have also acquired a Fronius SYMO 6 KW and Victron 250/70 CC ( in addition to my 150/70 and 150/45) to handle the large loads during daytime


After consuming 87 litres in Last one year for my 20 KVA gen and spending more on starter batteries and chargers and maintenance for the gen than diesel saved I have decided the gen should be run regularly to keep things in balance till the time Lithium becomes really affordable and I can truly dispose the gen

The problem is not whether icellpower is axpert clone. The problem is paying extra money to buy a hybrid and still buy a charge controller. Ipowerplus is a hybrid and is more expensive than icellpower which is not a hybrid. I was thinking if I buy the hybrid then no need to buy charge controller in future but with ur submission and that of big.. Then I'll go for the icellpower and later buy a charge controller

Good morning to everyone in the house, please i need you assistance to solve some problem with an inverter. The inverter is a 48v,3.5kva, with fangpusun mppt charge controller 60a/48v and solar panel of 300watts. it works morning till around 2.00am ,everday. The client need the unit to run 24/7 without stop. Thanks to everyone in the house.

Oga Pranil. How many inverters, charge controllers and other RE gadjects do you actually have. We have lost count

Pls house, there is this setting on the MPPT CC that I got, it is "load". The default value is 15.pls what does this stand for?and what's the implications if I reduce or increase the value?

Yiu won't like my response but I will say non the less. If you do not know the problem with this setup.. Then you have no business installing solar for a client. Nigeria is already filled to the brim with quarks posing as solar installers. It ends up hurting and doing damage to solar adoptation. All hope is not lost sha. Set back and learn the trade.. Its not even that hard.. That you can install solar panel on a roof or you are a good electrician don't make you an installer. If this question came from a Do IT Yourselfer then I would understand but not for someone holding himself out as an installer and having a client.

The truth is very bitter the poor abused client will now say solar does not work and swear off re and become the chief campaigner against re.

Op I'd definitely not qualified to be an installer.

Absolutely. It easier to see unicorns than a solar company embrace open source technology the way Victron has. From working directly with open source communities and ensuring that major software component of their offering has a free and open source alternative to publishing white papers about their various protocols and hardware accessories the same can not be said about other solar product. I know what a friend who reaches out offline is facing trying to get his iTracer controller to work with the open energy monitoring system emonpi. It was easy for me to DIY their connector cable thanks to their white paper which indicates which which is transmit, receive and ground all based on color coding. Their remote monitoring software and hardware have been completely open sourced and downloadable free of charge, their api is also open to be used with 3rd party tools which is what I took advantage of in setting up my own remote monioring dashboard.

hi the inverter set-up has 12-unit of 250w( i,e; 3000watts) mono pv,arranged in a unit of three in series and than the four units is connected in parallel ,this gives 112v open circuit voltage. it was observed that if the system is put off for about 1.5hrs during the day, the system works til-down each day. Thanks to everyone in the house.

NiyiOmoIyunade:
Boss! What is the nameplate VmP on your panels? 4 panels in series seems to be dancing rather close to the 145/150vDC controller limit biko. Most 250w panels have VMP in the 30 to 32vDC range and 4 in series may be able to make enough voltage to brick your CC or did you mean 4 parallel strings with each string having 2 panels in series?

And if I recall right someone here (maybe you ) played with 4 panels in series in the past and bricked his MorningStar. In a 24v nominal battery system and with this basic controller, I don't see any advantage you would get having array voltage around 120v.

To answer your questions, the EP Solar Max Array Size is determined by the formula [LBatt x Max Array VmP] so with a 60a controller, LBatt (Max Battery Current) is 60amps while your VmP (conventional two panels in series for a 24v system) is ~60v. 60amps x 60vMP gives you 3.6kW as the max array size with EP Solar 60a when used in a 24v system. Based on this and actual field experience you will be very okay with a 2.4kW array and safe up until 3kW of PV panels even (allowing a common sense margin of safety so we don't reach the actual 3.6kW limit)

You will need a DC clamp meter to accurately measure each individual panel in a string's contribution or lack thereof to the combined string performance. As often reinforced on this forum, I insist that no DIYer or RE professional worth his salt can get by without a DC clamp meter or suitable substitute - with a DC clamp, you will be able to test each panel's behaviour in live operations without interrupting or disrupting the circuit.

Please clarify what you mean by the 'chinese are vertical while the renogy are horizontal'

so just a lil update, so i popped into villa, and the sun broke tru the clouds for about 30mins, i observed 59.8amps instantenous current, an d 1722w on the epsolar cc, though it was steady, would display for a few seconds and drop to 1400w range. i now understand fully what u meant by overloading the array/cc,
from the 59.8amps instantenous amps i observed several times, i can conclude that my panels are ok, and kicking out juice...guess the cc clamped down on the current, not to exceed the 60amp cc rating. my batts sure gonna be happy during the dry season

Okay let me help you small.
You said the system isnt working till dawn
the sun goes down around 6pm, so it means from 6pm, client is on batteries, so around 2am system goes off, which means :
1. client depletes battery with heavy loads,,,,, bad
2, battery bank isnt correctly sized to accomodate 24hrs usage,,,,,bad
3, batteries arent charging well during the day,,,,,bad
4 village people are following client,,,,,,worse

thank me later

Please I want to ask a novice question.
I have two 12v 170amps batteries connected in series for a 24v setup.
Can I add two extra 12v 200amps batteries connected in series then parallel the two strings?

My rudimentary cal say I will get 24v 370amps.

Is it a bad idea?

It's better you use the same capacity and even similar brand in order to avoid story that touch.

With all these modules you are not enjoying solar. It is bad. Something must be wrong. Where are you staying? Just pm me for adjustments on the system. The system need to be overhaul and resized.

I think it is a bad idea- different capacities, different ages of batteries. You can have two separate battery banks and use a battery changeover switch.

Pls help

What are you exactly using the CC for? For most CCs it is redundant. You connect your batteries to the + and - terminals on the CC and your inverter to your batteries. However if you are using it to control output to loads like street lights, house lights etc light loads like that, that you want to time[/size][size=8pt] duration of use , then it could be useful.
