NiyiOmoIyunade: Nope Magnum is superb on it's own .. Sold & Installed several without issues as Oga George pointed ! It also has good after sales support from USA , few local source within and devices can be purchased/replaced like any victron component , Richmond can attest to that ! It depends on clients choice and budget ... Magnum MagWeb Monitoring Kit is also a powerful and cost effective tool for remotely monitoring Magnum inverters and accessories ! Nagode |

Update on my thin film panel experience: About 3 years or so ago, I got some set of thin film panels- each 100W @ 99+ volts. I installed 14 then and just kept 6 in store. I recently dabbled to a venture that increased my water need and hence power need. I therefore ransacked my store for leftover electrical materials from my building project and here are the results.

Re: Solar Energy, A Complement To FTA by durodee(m): 4:39pm On Feb 16, 2019 |
durodee:Materials: 1) 1 roll of 2.5mm copper wire -red (panels to knife switch) 2) scrap length of 4mm black and red copper cables (knife switch to CC) 3) 10mm multi-strand copper cables (CC to 200 amp 24v battery bank) 4) 100A knife switch 5) 30 amp MPPT EPSolar CC - bought second hand from Bigrover years ago! 6) Aluminum pipe ( left over from window construction) to serve as base for the solar panels 7) 6 nos 100w panels =600 watts Results: Instantaneous yields of between 18.5 amps to 19.9 amp around noon . approx 19A×24v= 456W using scrap materials. Opinion: Start with whatever you have; upgrade as quickly and as soon as possibly; you don't have to break the bank to enjoy Solar. 1 Like 1 Share

Also, you definitely enjoy the advantage of easy cleaning at will. 2. Yours in bold above is well spoken. 3. Advert - advert- almost on every slide is making the room so boring.

Looks good! Although at first I struggled with the cable gauges used especially 2.5MM wire from panel to CC. If possible you should at least match the wire gauge of the panel cables in the panel to CC connection. If I understood correctly, you have just 600 watts of panels deployed right now? You must review the suitability of your cable gauges if you ever plan to upgrade. How is the Knife Switch handling arcing with DC currents passing through when you (dis)connect the PV array? I have played several times with the idea of using a 200A knife switch as a manual disconnect from battery for my 60A MorningStar CCs (2 units with 1 unit to each pole of the knife switch) but fear nor gree me do am - the copper in the knife switch definitely looks like it should take it but you just never know especially with CCs & PV array fond of doing ~3kw each on a regular basis. durodee: |
Re: Solar Energy, A Complement To FTA by durodee(m): 2:10pm On Feb 17, 2019 |
NiyiOmoIyunade:Thanks! I do have other panels installed to serve my main needs. 6 nos Mono Solarworld 255W as 3S2P to a 60 amp Itracer CC ( done by myself) and 6 nos poly 170W panels, all in parallel to a 40 amp epever CC ( my first installation , done by an installer when I was a complete newbie, I did not even know the name of the panels). The unique parameters for the thin film DuPoint panels (100w, 100 panels, open circuit) preclude any thoughts of upgrading that SPECIFIC setup. Will I use the same wires gauge for voltages less than 100v? Maybe not! Even my Mono setup is 6mm @135v panel to CC. It is interesting to note the cables of the DuPoint thin film panels look like 4mm ALUMINUM to me!! Now to knife switch issue. I only put between panels and Cc and I use it because of the simplicity and the fact that I extremely rarely work on my setup during the day; almost always at night or very early morning before work- so the panels are quiet and I don't notice any arching. I don't have the technical expertise of you Oga at the tops! ![]() |
Re: Solar Energy, A Complement To FTA by Trippledots(m): 6:58pm On Feb 17, 2019 |
pls house is this normal? i have a very small setup. two 100w panels in parallel charging a 180ahr battery. i average 40w draw on the inverter but thats not the issue. My battery measured 12.9v when i got it but i haven't been able to get it up to 12.7v ever since. i added a laptop charger to the solar input just to boost the input power. laptop charger clocks in at 89w and the battery voltages rapidly rises once there is power supply. but i noticed that once the battery voltage gets to 12.6v, the voltage drops to 12.4,3 and 2. looking at the wattmeter on the wall shows the charger watts drop to less than 3w. my concern is why is the pwm cc disconnecting the dc source at 12.6v when it is set at a float of 13.8v? |
Re: Solar Energy, A Complement To FTA by mctfopt: 7:30pm On Feb 17, 2019 |
Trippledots: It's not normal. I really do not understand the part about adding a laptop charger to the system. You mean you added the output (in DC) of a laptop charger to the input of the CC or directly to the battery? I think the problem may likely be the PWM CC. Try getting an inexpensive MPPT ,and connect the two panels in series. Do you ever charge with the inverter? If you do, what voltage do you get when you do. 2 Likes |

mctfopt: as for that mppt, i thoroughly researched it before buying that pwm and i felt it was an overkill for my system. i may have to buy it after all. btw, that powr model is actually a clone of the makeskyblue original fyi |
Re: Solar Energy, A Complement To FTA by mctfopt: 9:03pm On Feb 17, 2019 |
Trippledots: That clone issue is hard to prove ![]() There are these back and forth accusations between these two. The difference between the two is not much: by the way I have seen both and I don't really see any difference between them hardware wise apart from the software little difference. That being said, getting an MPPT won't be a waste of money. I'm still a bit confused on the part the laptop charger plays. Trippledots: Also, how is it much of a difference to your landlord if you change your panel connection configuration from parallel to series as I think you already have two panels connected in parallel? I thought the problem he has is with you adding more panels. 1 Like |
Re: Solar Energy, A Complement To FTA by Trippledots(m): 1:39am On Feb 18, 2019 |
mctfopt: THE makesky claims to have software updates, thats my reason for believing they are the oroginals @laptop charger...i simply spliced up the power brick output and paralled it with the pv cables. thats all @landlord...well i mentioned him because i would have just added more pv modules rather than gamble with a power brick as dc input to my cc |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 11:51am On Feb 18, 2019 |
duwdu: I am looking at the manual it's written 320vdc as the normal operating voltage but the attached picture reads 240vdc. Irrespective am trying to understand what this means, does it mean that it is until I have sufficient number of panels in series totalling 240v that the stuff can work? So if a solar panel Max PV is 32v I will need a least 8 panels before I can use this inverter? |

Re: Solar Energy, A Complement To FTA by mctfopt: 2:27pm On Feb 18, 2019 |
Trippledots: Fangpusun can handle higher current more than any of the other two and most users complain of being unable to use more than 6mm size cable on either the pv or battery terminal section of the MakeSkyBlue or Powmr CC, in Fangpusun you can easily use a 16mm cable on the cable terminating point of the CC. Fangpusun has more customization and data logging ability too. If you can afford it, go for it. 1 Like |

NiyiOmoIyunade: Knife switch definitely NO I don't recommend it even for AC they tend to get loose and create hotspot after frequent use . Also Knife switch will not only arc but continue arcing after opening on heavy load typically AC contactors for DC duty are derated despite having ARC chute ( by 1.41 RMS ratio) also normally the arc chutes for DC are different to limit high voltages which might damage the connected equipment The attached ABB article explains in detail

Re: Solar Energy, A Complement To FTA by pranil(m): 11:39pm On Feb 18, 2019 |
ojeysky: The MPP solar mentions 120 to 450 V DC as MPPT range with ideal as 240 V DC for max efficiency and max 500 V DC for series connection Min you need 120V / Vmpp of panel and max 500DC /Voc of panel - best combo is 250V DC/Vmpp of panel Also take care when selecting fuses /breaker etc . They must be rated 250 or 600 V DC based on your final selection . may of them in market like midnight solar are rated only upto 150 V DC
