DieITou posted a topic in Starting In Solar? Feel free to introduce yourself,Hi everyone.
Need a bit of advice please on the way forward with current install with the max amount of panels I can add.
Currently the system is about a year old. Kodak OG 5.48, 8x Canadian 365w KuMax panels (8s) , 4.8kwh Shoto Lith.
Specs on Inverter: Max PV 5KW, MPPT range 120-430 VDC, max VOC 500 VDC. Not 100% confirmed but max input current on one or two sites 18A
Panels spec on 1000 W/m2: Pmax 365W, Vmp 39.8V, Imp 9.18A, Voc 47.2v, Isc 9.75A
The system is running great, powering everything on essential side, stuff left on non-essential is geyser and oven (got a gas hob). Got a plan in mind for the geyser so thats why the question regarding more panels and helps a bit with overcast.
A friend of mine who installed the same time as me and his panels are out of the same batch as mine is planning to change his 6 panels he has to 450w+ panels.
At last I can get to the question. I'm thinking of taking over his panels and maybe running a 6p2s ( 4.38Kw 18.36A, VOC 283.2v) or 7p2s (5.1Kw, 18.36A, VOC 330.4v) configuration. but with the series config I'll be pushing the input current to 18.36.
Any input will be much appreciated. roof real-estate is not a problem can accommodate parallel strings and is pointing 357 degrees (N)

I have been lurking in the forum for a while and am considering a grid tied installation.
I would like some advice for or against if anyone has an opinion or experience with these panels above.
I had never heard of them until 2 days ago, but they do seem promising based on what I was able to find from web research, YouTube, etc.
They were suggested by the installer.
See attached link, http://www.znshinesolar.com/product/zxm6-nh144/
The installer I may go with has done some big commercial installations, formed his own company and has done an installation at a family member's house and at his colleagues houses. So comes with a good reputation.
He suggested the Deye 5kw inverter, but I am leaning towards the sunsynk based on everything I have read here.
Other informative details: single phase, prepaid meter, 500kwh monthly usage, johanesburg location, solar geyser, gas stove. Have a separate Ellies powercube ups for router and fibre. Also have the mecer 200ah llifepo4 second Life battery and small 600w inverter to charge laptops for working from home (this was my first trip down the power backup rabbit hole :-). Would like to keep the essentials going during loadshedding and subsequent outages.
I'm on solar now for 6 months, but geyser (200lt, 3kw) is still on Eskom. I want to go completely off grid. Which is the best geyser alternative? Solar, high pressure/low pressure, retrofit or gas? Considering purchase price etc.
