idea
bringing 100 plug points down from ceiling and IT installed cables in two days ...now fitting of trunks... 40 men hrs
emf free installation/ shielded till workstation
50 A Single phase system/ with victron inverters single phase 15KVA possible i choose to upgrade from 12KVA + 15KVA so now 30KVA usable without tripping power from ESKOM rest of energy will be supplied from batteries solarpanels and wind 50 A Einphaseneinspeisung 12KVA Einspeisung war in diesem Haus vorhanden , mit 3 Victron invertern und powerassist mode kann bis zu 15KVA also knapp 30 KVA benutzt werden, hierbei ist man von der Batteriekapazitaet abhaengig inwieweit man 30 KVA benutzen kann. Das kann aber in einfacher weise mit Sonne ( Photovoltaik) oder Wind beliebig erweitert werden ohne zuviel Geld fuer die Batterien ausgeben zu muessen
in serverroom 4 internetpoint/ network and different plugs to check systemperformance
lineconditioner/ 400 A circuit breaker 24V 5000W inverter
plugs in rooms / emf free installed
inverters linkable with cat 5 cables 3 phase or single phase possible- es ist einstellbar ob man ein 3 Phasen Netz kreiert oder 1 phasig 15kVA zur Verfügung stellt
trunks dc and ac wiring
energy saving hotwater with gas
kitchenette/ microwave once exceeds 20 A inverter goes in helpmode and transfers rest of energy with the help of the batteries- um Hauptsicherung zu entlasten 12kW max wird über power assist Energie über die Batterien zur Verfügung gestellt
ups and downs on top as well night time mode \balanced
südafrikanische Steckdose ( verpolungssicher ) mit DC Sicherungen sowie Quattro Geräte von Victron energy - south african plugs emf friendly as you can t reconnect 180 degree as you could in germany therebye switching neutral or phase and so running live all the way up to the bulb and back to the switch if single pole switch used-
office area
5000W inverters
battery rack
3 inverters and db boards
load stabil output 230V AC
earth leakage and circ. breakers per inverter
Main Switch
emf free installation with surfex cables/shielded
shielded cables emf free network 1 GByte
seperate earth emf free installation N bus interconnected inverters /generator Wind/Solar
trunking for earth and cables
earthed trunking/ to keep it shielded
borehole pump and sw pool pump with seperate db boards as well blue plug in case generator is needed when powerfailures longer than 2 days without sunshine very unlikely- backup Sonne mit Dieselgenerator , bereits vorbereitet würde benötigt bei 2 Tage Komplettausfall und keine Sonne ( verregnet )
gate motor inside and keypad to drive out in case remote won t work- falls die Fernbedienung (Batterie leer) wider erwarten nicht funktionieren sollte , ein keypad am Tor
key pad and intekomstations with pin hole camera inside writings are 3 leds for night mode not visible- Tormotor wird über keypad geöffnet , Kamera mit Öffnerfunktion für Büro und Wohnhaus
gate motor running on DC supply 12 V and get charged over photovoltaic panels mounted on the roof- der Tormotor mit 12V backup ausgeliefert wird über die Solaranlage Dach indirekt nachgeladen
Microwave and kettle as well coffemachine , power assist kicks in and the main from eskom won t be overloaded as the energy "comes" straight from the batteries ( via the sun ). Bei Kaffemaschine bzw Mikrowelle werden ( frei einstellbar) 19A überschritten , die Energie wird vom Inverter bereitgestellt d.h die Batterie speist die extra Ampere in den Stromkreis ein ohne die Hauptsicherung zu überlasten (power assist mode )
stand alone inverter 5kW supplied from Eskom powerassist mode another 5 KVA from batteries in total 10 KVA- 5000W produziert vom EVU , weitere 5000W kann der Quattro über power assist zur Verfügung stellen ohne das die Sicherung "fliegt"
remotely controlled supply line at the moment you can use 19 A from a 30A circuit breaker in case you need more energy powerassist kicks in and supplies the more amount of energy needed from batteries
second inverter standalone Eskom or LC
energy flow can be delivered either from ESKOM or Lineconditioner always 230 V output
second bus bar 600 Amps
bus bar capable 600Amps used to have equal 24 V DC supply for each inverter same cable length
circ breaker 24 V DC 400A for victron energy 5000 W inverter
from Eskom supplied 1500 W by 225 V AC stabilized by Lineconditioner 230 V AC and deducting 400 W produced from the sun
cloudy weather producing 120 W
at the moment 10% from the sun stabilizing 230 V AC supply
2400 W used at the moment in the office
summary of different load scenarios and backup sun as loadminimizer
2700W consumed/ loads 1100W produced from the sun
227 V AC incoming stabilized to 230 V
by adding a Lineconditioner, you will achieve a stable grid and no noise / harmonics coming in from the electr. supplier
Büroarbeitzplatz- office work space with add on working stations- keep it simple
voltage line conditioner stabilizing towards 230 V AC - egal welche Voltzahl 210.......250 V AC der VLC wird die Spannung auf 230 V AC rauf bzw, runterregeln
aesthetically the black surface looks better but performance wise and installing it s better to go polycrystalline you need 4 panels instead 1 of the polycrystalline so possible mismatch problems alltough amorph are incr. cheap 1/3 of the price
amorph heats up quicker and reduces output faster than polycrystalline and you need double the space on the roof cheap price but more mismatch possible
test the best
at the moment savings from round about 4 A almost 900 W
solararray producing 1265W
stable output 224V from supplier 229-230 V made from machine/lineconditioner
1,6kW peak is producing 1280 W 48 V DC system
house uses 2200W getting 1100 W from municipality rest comes from the sun
first will batteries kept to floatlevel later power gets subtracted from supplier produced 970W 170W into batterybank 800W subtract from municipality
720 W amorph installed 48V DC system

680W polycrystalline 475 W amorph produced at the moment 75,5% poly 66 % amorph

african sun is making the tefla yellowish but still same output- die starke afrikanische Sonne hat die weisse Folie gelblich verfärbt aber die performance hat darunter nicht gelitten immer noch dieselbe Wattage
deutlich erkennbar (gleiches Baujahr ) die Verfärbung der Module
2,2 kW into household 0,8 kW produced fr. sun from supplier 1,6kW
kristallines Modul sowie amorphe Module Preisvorteil 2/3 billiger als kristallin Performance aber weniger 20W modul
lineconditioner incl. supply is on 225 V AC LC keeps it on 230 V AC
same amount of power installed but 2 - 3 times more space required/ amorph against polycrystalline
awkward is sometimes the blueish and blackish difference in appearence but normally on top of the roof not visible
amorph 0,55 A flowing with 80V seriel connection- 80V 0,55A fliessen bei 4 Modulen seriell verschaltet~ 44W
900 W installed 48 V DC system polycristallin 725W/ 17.11.2008 amorph240W bottom installed produced 210W
crystaline module producing 1,27A more than double the amount of amorph
polycrystalline modules use less space , less cables and produce under these circumstances almost double the output, pricewise the modules are half the price - so you could built up with amorph panels double the output instead 900 W almost 2 kW.....- Die Module aufgebaut kosten in etwa die Hälfte im gegensatz zu polykristallinen da mehr Unterkonstruktion benötigt wird- die doppelte Fläche wird benötigt, kein Problem aber dadurch hebt sich der Preisvorteil wieder auf. Einzig bei bewölktem Wetter sind die amorphen Module besser.
