About the same cost I paid for the 5 inverters, 3 controllers, 5 circuit breaker and the 5 residual circuit breakers. So is one box better than 18 individual ones?
The finished project so far. My neighbour reckons one can buy a VIctron box with 3,500 watt inverter, 100 amp solar control and Residual circuit breaker and circuit breaker, plus amp charger all rolled in one box for $3,500.

Beautiful sunny day today, at Dululu.
Some say light travels only as a wave, some say light travels as both a wave and a particle. It's a mystery to consider which.

Will add water to 5mm above max level and at max level means to add more water.
Notice the interior plates are getting exposed. (Red arrow), I added 500ml of distilled water to each cell, and this is not near enough yet for some cells.
The water level in the batteries is misleading. Half way between max and min should be OK? NO
it means your cell plates are exposed.

Sunny days charge the system to near full by 9:00 am. Things are running fine.
@prologic Interesting read from their website, but how much do they cost?

@prologic Yeah so it's cheaper to purchase a 240V fridge rather than a 24volt one, much cheaper and easier. In fact the only things I can't do so far on my off grid is run a circular saw, weld, use a toaster and an electric jug. Everything else seems ok on less than 900 watts. I do believe you can get 24volt air conditioners too.

What is set up so far, fridge has it's own dedicated inverter 560W, the washing machine, lounge TV and bed fan has another inverter 900W, the water pump has it's own inverter, 560W, all three are running OK, except some get hot during the day from use.
Our fridge went through the night off grid for the first time, no worries. Uses only 6 amps, 150 W when running, cheap compared to the water pump.
System so far, fridge now connected to solar.
First night running off grid. Seems happy, voltage in bank is 25V, around 80% full.

Tree fell over nearly killing Diane, near chook pen crushing the railings. Big clean up this weekend.
Been getting carbon from the water during charging process. Apparently it's normal part of KOH reacting with C in the air. You clean the cells after 8 yrs of carbon build up.
Just swapped it over for 50Amp fuse, notice for a flash brief 1/2 second I saw what might have been 27 Amps as the pump turns on, ie initial rush of current, as the 516W motor is very inductive in its draw of current.
The water pump is 516 W, draws 20 Amps and runs on 240V using 2 amps. So why does the fuse trip all the time?
Can't understand why this Inverter keeps throwing the switch? The Fuse is rated at 30Amps but keeps on tripping? Weird.
@prologic True, they want you to consume more, not less. This is a fundamental problem with society. I remember once a 8 yr old PNG boy cooking breakfast using a single stick with 10 reef fish laid across the stick fire. An Australian boy would have used a wheelbarrow of sticks.

Found a preloved one in Blackwater.... How good is the Lord in heaven.
Runs on just 400 watts.

Cannot find a washing machine which uses less water and runs on less than 400 watts of power. The LG 5Kg Fuzzy Logic is no longer being made. Fisher and Paykael also no longer make the 7 Kg smart drive machines. Most stats do not include watts on the specifications.
50, 000 watts per day? Boy. I would like to get it down to 5,000 watts per day. I only have in theory, a battery bank that stores 15,000 watts per day, leaving some for cloudy days, etc.
Got our power bill today $430, the off grid cost us 19,000, so will take only 11 years to break even.
Why and how are we using 13 KWhr per day? Fridge 3 units, water pump 3 units (6hrs perday) bore pump (3 units) 6 hours pumping per day, fans (0.5 unit) lights (3 40w, on 5 hrs) (0.5 unit) that's only 10 units accounted for?? bread maker, washing machine, TV, water heater 20litre (arrh? )

On a sunny day, now I get 60 Amps of charging, but on overcast days things are not so good.
Removed all the solar panels, and wired up new strings, one on left are Trina 370W, 2 in series 2 in parallel, making 4 panels in total, gives 30Amps\nAnd 6 on right are my older Zeus Apollo all 45 v and all six in parallel, gives me 30 Amps also.

Yeah I learned that a single dud, say 2 amps drags in parallel all other solar panels to 2 amps, and a single dud in voltage say 20 volts drags all other solar panels in series down to 20 volts, So One should check every solar panel first for volts and amps.
@prologic Possibly, will have to undo string wiring and check each one individually, plus also check why MPPT given 75 Volt performs so badly with 5 amp output?

The theory never matches the practical performance.
At least now, I have learned how to do this, measuring current from a solar panel. The 8 yr old panels I used obviously are making piddly squat current. At least I have my 4 year old new, 45 V 5 A solar panels, should give me 28 volts for the eight of them, assuming I get 3.5 Amps off each one?
I suspect my solar panels are duds, not making enough current, Confirmed email from David, my supplier from Iron Core Batteries. I will have to stop charging the batteries with little amounts, turn off the system, remove all solar panels, and start again, measuring each solar panels individual performance first.
Diane used the water pump heaps yesterday, plus water controller switching on, the bank dropped to 22Volts. What does this mean? How much battery storage do I have left? I suspect 30% but not sure? And do I get really big bulk adsorption charging currents in the morning today?
I will be interested in how the batteries faired on their first running of the water pump over the entire night, and morning charging rate? Currently at 7pm, the batteries were at 25V or about 60%. That's a fair drop in storage. I suspect the 500amphours is not achieved as yet.
Getting 150 watts and 5amps off the roof.
Showing MPPT B, the second one.
Cloudy showery day, still got 200Watt and 6amps going into battery.
Some facts from MPPT (A)
Got the MPTT to connect to the computer.
@prologic Possibly considered portable camping equipment, where total safety is not important.

The water pump draws 18 Amps, changing the float voltage from 28V to 26V in about 10 minutes of operation. The solar panels respond with charging 6 amps and 7 amps. After resting the pump draws 0.6 A and the battery bank is back to 28V and float full in about 10 minutes.
Close up view of RCD and CB, the neutral and earth wires are joined in Australian standards. The CB is limited to 4.0 amps, about 930 watts.
The first inverter is now up and running. wow. Will test the system now during the week.
Running a 60w 240V light bulb costs the battery bank 2.5 Amps, so running a single 240 V light costs 24 Amp hours, about 1/10 of mine total storage.
Tried out my new changed inverters and they do not have an active neutral, they have an dead one, which it is supposed to be. Seems like India has different wiring standards, and they sell products to Australian without changing to our wiring electrical standards. Go figure !
Remove the earth wire from one jumper and move it carefully to the other jumper, like red arrow. Now you have one active wire and one neutral wire.
Why isn't this the default for Australian standards?

This is potentially dangerous, if you use a RCD, it will not work, so its a cheap comprise for portable power appliances. After 2 hours of reading found a updated manual solution:
Discovered my Phoenix 1200VA inverters are cheap and nasty do NOT come with neutral and active outputs by default, they come with two actives instead, ie floating.
Uninstall, install software again, no luck. Seems can't connect to the MPTT. Will try old windows Xp software?
System so far, red arrow shows my attempt to VE direct USB to MPPT.
On adsorption, the incoming charge current is between 2 and 5 amps, not much I thought? Something wrong?? Have to get clamp ammeter to confirm this?
Begin by installing the DC DC convertor, change the voltage down (red arrow) to 9.0V, so it changes 24V to 9V to run ammeters.
Details of where the second string begins, note coloured coded wires.
It has taken a full week to achieve this. Must find out what the Amp charging is? The second string will achieve the charging rate faster of course/
Ready to install the next string of panels, 2 in series, 2 in parallel, 75V @ 10 A. The system has settled down down, fully charged and floats at 27.6 V.
The Australian Government announced that in July, all farmers can grow GM wheat, oats and soyabeans. The list of Genetically Spoiled foods is growing. Now wheat is on the list. This means nothing in the shops can be eaten or trusted to be eaten in a healthy way. I suppose most people think eating GMO food does you no harm. Think again and do some research.

The system is running crudely.
@prologic Can't do until voltage of bank settles down, still running at 27 volts instead of 22 volts. So the chemistry is still getting used to reactions. Plus my ammeters are not hooked up yet. I have ten of these so will be able to verse you on stats soon.

@lyse Ah yes, the easiest way to remove electrical shocks.
72DC at 10 amps can potentially kill you. I note once connected to the MPTT the voltage drops to 39VDC.
I will be working on the second solar panel array today, same as the first one.

Our system is up and running now, with open end voltage of one array at 75VDC and when connected to the MPPT drops to 27 volts. Not sure of current as yet, my ammeters are waiting to be installed. The batteries gurgle, making H2 gas.
