Theres is no way you can talk about Luminous when you are talking about flooded battery.
First of all it charges battery at 16amps and secondly it can't disulphide (equalize). So among the two PRAG might be your only choice.

PRAG offers you battery type selections which keeps your charging as close as possible to the battery manufactures specs and also gives you the DOD switch which is a great feature for renewable energy battery maintenance. I wrote about this in details in my last review of PRAG inverters.

earthrealm:
@richmon, thanks for the info.
nolonger a big fan of lumious,,..

1. it doesnt display batt life/status.
2. it ruined the negative batt of 2 24v setups i hv
3. doesnt desulphize/desulphate.......

though i was thinking the 3.5kva 48v system wud hv beta charging algorithm/current than the 1500kva.

so am gonna settle for prag 4kva 24v as u adviced.
whats the minimum size of cable for the inverter ac input/feeder...i mean prag 4kva, wud 4mm be ok?, conflicting views on the internet....intend to put a 50amp breaker too

saw the green prag 130k on jumia, while the blue one was 175k,....wondering at the discrepancy.......guess old stock or something

richmon74:


Well you need to check up with jumia again. I bet you they can't sell it for 130 because they don't even buy it for that price. The colours doesn't make any difference as I told you before. We are the cheapest reseller of PRAG product. We're the only one that can give you PRAG 4kVA 24V/48V H for 136k. The inverter comes with Standard Battery Cable and AC IN/OUT wires so you don't have to bother yourself with the cable sizings.

If you are interested contact us it and for any other PRAG products you see on www.buyright.com.
We also offer professional advice on product selections and installation as additional benefits.

next who has gel 2v 500ah to 1200ah batteries..

secondly trying to choose btw flooded and sealed gel batteries...both hv major strengths n weaknesses, really getting confused..
can the pros chime in....wud prefer persons who hv used both types to share thier experience

Please, All the Professionals in the house, come to my aid... I just got delivery of a 5kva transformerless inverter from UK but im confused as to the installation and grounding required for the solar panel array and the inverter. (I even read somewhere that the +ve terminal of battery should be grounded). I know that most of my "Oga's" here have dealt with transformerless inverters, Please help me with the knowledge to install this piece. Thanks in advance. @richmon74, kiekie1, earthrealm, chris81964, tnycee Goodday seems like a Axpert branded inverter . Talk to oga chris81964 has installed several.

Ive attached a photo to show what the inverter looks like.

chris81964:

The inverter is manufactured by Voltronic Power. Different people sell it under different names. Ground the PV. Ground your combiner. I would not do a positive ground of the batteries. I have instructed my people to do negative grounding. Visit the company s website. They have a manual on their page.
They are pretty OK inverters. I run separate charge controllers. The 5 Kva is more finicky.
Good luck

DUNKA:
seems like an Axpert branded inverter. Talk to oga Chris81964. He has installed several. Also google a South african forum i.e. powerforum.co.za and read through they have a lot of info and valuable tips on this particular inverter over there.

richmon74:


It is always an argument btw UK and US on which battery polarity to ground. UK says +ve and US says -ve. But for your safety, do not ground any. Do the standard earthing of the AC line n chassis. They are very durable inverters to my surprise. I've installed a couple of them in both residential and commercial environments and they are still working great.

Braaad:
Thank you very much for your response sir... One more question please...
can I loop the AC and chassis ground together or should the chassis have and solar array have a separate grounding?? Thanks in advance for your response

help house, am considering this inverter protek 3kw.,,,any reviews from sers

https://www./protek-3kw-inverter-4260428.html

kiekie1:

Why PROTEK ?

RipVanWink:


i dont want luminous, since my batts r flooded, prag i learnt does nt hv as highlighted in tab 1 in the pic below, ie it doesnt hv inverter off, charging on, inverter output off, luminous and other inverters hv this common setting, wonder why prag doesnt.

must power doesnt appear to b a favourite here...i wonder why...does it hv issues?

kiekie1:

OK lol, I was of the view that you were totally OFF GRID bt that's Prag feature for you. Contact me if you need a 4kw or 3kw with OFF CHARGE & BYPASS MODE , its available ....

RipVanWink:
.

ok gr8, what make[s] do you have?

This week I got invited to be a guest speaker at Yale University Law School where I will talk about my experiences doing business in Nigeria as part of their Doing Business in Africa Series. It is a week long series and I am extra privileged to be able to stand on the podium and relay my experience.
