earthrealm: yeah, i was using option 6 - open lead acid 14.8v, ytday i switched to option 7 calcuim-15.1v, lemme observe and see, though am seeing some improvements already yes i use the energy saving function, once your loa is less than 35w, it will trip off, a bit iffy for me on cold nights when i have only 2 energy saving lights on,16w each, it usually goes off...unless its 18w each.
have you checked the idle consumption when on energy saving mode?
is same bro except the inverter didn't detect any load and switch off
earthrealm: errrm, sorry .want to make some clarifications, must be the 2 days that i had my gen on to charge my inverter than confused me...something i hvnt done in more than 6months. so on gen the mopower charging voltage remained on 51.6v and current on 22amps, no matter the setting [i blv cos the batt was low, the charging algorithm is making it charge the batt slowly, or it doesnt like the not so clean gen power?], it stayed like this for 3hours...
phcn later brought power, and i was now monitoring the display like a hawk...i saw the voltge go as high as 59.6v and 31amps [something i dont recall ever seeing b4 unless on equalize setting], it later settled to 53.6v and current abt 2amps, wch i believe is float. seems mustpower has only 3 stage charging, unlike prag that has 4 stage. i am using the 15.1v setting now, and not the 14.8v i have always used...lemme watch and see if there is any improvement
@juo & all, how do u calculate the self consumption of the inverter....wch device do u use?
earthrealm: 100 effing watts!!!!!, and the clowns wrote <25w on the manual, ...damn!. so pls clarify the dc voltage on the display when its charging, what charging/batt setting do you use, what type of battery do you have
@bigrovar most common inverters dont charge with 58v for a 4 batt setup, prag is even 13.3v, mustpower stated 14.8v but i dont see that when my batts are charging
the manufacturers are all liars. My luminous 1.5kva Self-consumption is 40w, this is 960wh in 24 hrs. Believe me I have seen one unless 7.5kw cyber-power consume 350w. How do you expect your batteries to do 5 years with this?
chris81964: We have not experienced the failure with the 30 amp 100 Vunit. However the higher voltage units are failing. Fangpusen is aware and they have not provided a solution.

I want to share my setup with the house so as to serve as a source of motivation to new DIYers that would come across this thread because it's the same way i got the needed info to do mine. I have read, watched and studied so much in the past years as regards to solar and renewable energy that I was able to design, procure and deploy my setup all by myself and with help of a couple of friends. I did make use of some carpenter guy to help mount the panels on the roof following my instructions through, and also got my electrician to run load separation cables for me. However, there are members of this forum who have been immensely helpful to me by answering my plenty questions and worries, I am very grateful to Mr. Chris of AWPS Renewable Energy, your love n passion for the job is unquestionable!, Dunka, your motivation is next to none, Frankie the able supplier and a brother, George_D da boss!, thanks for the emails! and all the contributing members here, y'all are the best. it has been a very wonderful experience and I thank God for the opportunity.

It is important to state that these items were acquired over a long period of time, infact, it took me one year plus of self disciplined money management, savings and forfeiting so much to make this happen maybe because of my taste in quality but from experience, i have learnt to go hard and go once! at a point i was sending money monthly to Frankie so as to secure a price point on the panels when the dollar was climbing like crazy. The most expensive item to get were the batteries as you had to buy them once. My candid advice to anyone is to start small, make a checklist of needed items and bit by bit, you will be striking off the ones you get as time goes on.
Panels were run in series/parallel strings of 3X5 to a combiner box with 5 breakers. All panels, inverter, CC and Combiner box were Grounded. 6MM ammoured cables from panels to combiner box, 10MM from combiner box to CC. Battery interconnect cables, CC to battery bank, Inverter to battery bank all 50MM Extra fine stranded Welding cable. Although a little more expensive, these cables handle any load comfortably and have never felt a tad warm to the touch at all and trust me, i have pushed them to the max all in the name of testing.
Seeking to achieve an 'almost' off grid setup, I went for that much number in panels and the result of having an array sized to cover the worst time of year, is that you get quite a bit of spare power at peak sun times. Therefore it makes sense to divide your loads up into base loads and opportunity loads. My base loads are 1 large Refrigerator (on a timer running 7AM-5PM daily), 1 always-on 24/7 Freezer, water pumps, computer gear, chargers of all sorts, lighting, security lights consisting of 8 X 15W energy saving bulbs (looking to change them to LEDs of less than 10W if i find them), an always-on Apple MacMini I use as my media server running a PLEX server serving movies to all TVs and smart devices like Roku box, Amazon fire Tv stick, and one Xiami Mi Android TV in the house, 2 standing fans, as well as sundry occasional appliances,power tools and other usual stuff; washing machine, iron, juicer, blender, microwave and hair blowers.
Most mornings, I wake up to a battery bank that is between 68-75% except on days i play the PS4 pro or xbox1 all night, i have seen 66% in the mornings, still under 50% DOD so not too bad and I know that my batteries have not yet been broken into very well. By 1-2PM batteries are already in float so the excess power are dumped into opportunity loads like running ACs, boiling water and cooking using the Induction cooker running at max power till like 4PM. I have seen max PV output of 3600W+ and my area in Abuja is very dusty, so many untarred road around my hood, panels were covered in dust from the next day after installation! and we have not seen any rains yet so i believe there is tendency for better output when the rains come.On average i harvest around 14-18Kwh daily. I have been running the system TOTALLY off-grid since the 10th of March.
I used the Wifi extender to extend my WAN and use the Ethernet jack to plug in the Midnight Classic CC to my home network, so i can monitor from PC and phone w/out having to run a long lan cable to my router inside. Got for less than $20 on amazon and works like a charm.
I use The smart plug to plug in my fridge and set it on a timer so it automatically comes on @ 7am and shuts off by 5PM daily. I also use it to monitor energy consumption in real time or over a period of time, very helpful to calculate all your energy consumption.
The smart switch i use to automatically turn on the whole security lights @ 7pm and turn of @ 6:15 am daily. and just like the smart plug, they both can be controlled from anywhere in the world from the app as long as u have internet and i have tested this, it works perfectly.
I am a geeky kinda guy so I love me some home automation and i have had some Phillips Hue lighting in the house, all devices in my Home theater setup are controlled using just a single remote-- The Logitec Harmony elite and all these devices can be controlled via voice with Alexa on amazon echo dot, pretty neat and works for the TP link switch and smart plugs too. I hv 10 Terabytes of Movies, TV series and Anime all in HD and running perfectly on the media server 24/7 with the beautiful interface of PLEX (guys u need to check it out, its simply your own NETFLIX @ home) For internet i use the NTEL unlimited package so everything is always ONLINE... I share my home wifi for my neighbors and they can watch movies on their phones and tablets as the media server can comfortably handle multiple media streams at once without issues. All these are possible because the sun gives me free Energy!
I cannot state how lovely it is to have uninterrupted power supply, something people in other countries take for granted. I think going solar is the best way forward for us here.
Ok!Sorry guys for the long read , however, Your comments, criticism, corrections and questions are welcome..
this is nice congratulations. Will definitely contact you for that TV maybe is something I can afford
Facing same thing now after topping last week. Imagine waking up and seeing your battery at 24.8v sad, it was 25.3v before the top up. Any little load you will see your battery draining like a flat tire. I have decided not to top once a year but twice. Once the water drops a little I will top it. I have experienced it before so it won't be an issue this time and I will not bother to equalize this time cos when I did before there was no immediate improvement. I know it will pick up after few weeks. The question is why must Trojan battery (T105) loose efficiency after topping? Great battery though
Gptech: . Nor mind me, just trying out the screen recorder app. Ok go to settings - About phone - tap the Internal Memory repeatedly for like seven times - then select phone 1 or 2 depending on the sim slot you inserted your sim - scroll down abit till you see 'set preferred network type' - select WCDMA only.
with what Sir Chris told me and I concur Fangpusun is a clone of Outback 60A & 80A (I have not seen Fangpusun 80A with it's features sha!)
However, for me, Fangpusun 60A is rugged just as the real ones and it is cheaper than outback CCs generally, I believe people with bucks prefer midnite solar to outback because of it network /internet flexibilities without buying additional mates which outback requires (also buying additional mates makes outback really expensive).
in addition, I expect fangpusun to cast the design of 70A in the like of 60A,80A series. this has been giving me worries why as high as 70A will come in structural cast of lower fangpusun CCs of 40A, 30A etc.
Has anyone observed that too? maybe sellers here can help me out, pls. info is needed! I am tempted to think 70A could have been a stamped nameplate of fangpusun.
don't forget the device is a clone, if you change the design is no longer a clone
A.Pls can you show the calculations you used in arriving at No 2 & 3
B.if my battery spec sheet says Max charge current 25A, how then do i regulate the CC not to supply more than this? 33A is in excess
C.Pls what's the difference between max rated power & max array power
D.In the morning, at what point will i know that my panels are producing enough "juice" to power my loads, what parameter will i be looking at on the CC
I ask the above cos some folks will say they put on their fridge btw 11am-4pm
Why 11am? Why put off at 4pm? What parameters informed them to turn on & off the fridge at that time?
Thanks Sire
I believe your husband is using your id to type this for quick attention. Cos the person typing this is well knowledgeable for advise
