At this pricepoint, OP might be better off with a Victron 5Kva - premium brand, similar wattage and at least 100k less with a rich open source ecosystem for monitoring and control.

I think there is also the wonderful 'powerassist' feature in the Victron which the Magnum lacks ....

kiekie1:


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

Magnum 4348v ...N920,000

Yes you can use inverter and battery as standalone power system design !

OgogoroFreak:
you mean once I buy this inverter and buy batteries, all is set?

NiyiOmoIyunade:
Most definitely Magnum is a great inverter.

But at that price point you quoted, the inverter which gives the best bang for buck is .....

kiekie1:



Sorry am just seeing this... Price quoted is for inverter and display Sir !

NiyiOmoIyunade:
You are correct my Oga.

But just that all these el cheapo inverters and devices give us a chance to exercise our engineering talent and push things to the limit - the learnings thus acquired from hard experience are invaluable.

I am definitely porting over to premium soon, just waiting for a milestone to give myself an excuse to purchase it

I agree and he communicates well unlike some other seller that I know on this thread

Oga Niyi,

Thank you.

I decided to tow the path of the silent observer.

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.

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.

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.

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?

mctfopt:


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?

Yes pls.

I think the problem may likely be the PWM CC. Try getting an [color=#990000]inexpensive MPPT [/color] i have an issue with my landlord not allowing pv installation so i really cant increrase my panels as i would want,and connect the two panels in series. Do you ever charge with the inverter? nope, its a cheap 500w car psw inverter If you do, what voltage do you get when you do.

Trippledots:


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

mctfopt:


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.




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.

what do you think about fangpusun cc as against makeskyblue or powmr?

Good-day house,

Am in need of 5kva 48V inverter with low idle power consumption (preferably hybrid inverter at a good price point). Kindly point me in the right direction.

NiyiOmoIyunade:
Looks good!

ojeysky:


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?

pranil:


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
