Hello gnubie and b.james This is my last 3 month bill. I have since changed plans so wait and see, hopefully it will be similar. I'm with AGL Our average daily use is approx 8kWh (2 people). For approx $1000.00 AUD it's hard to justify adding more solar Guy

I refuse to change now that they're installed

I know I'm off topic, what programme do you use for drawing

I saw comments that we had problems with mounting panels etc. due to Australia being at the bottom of the world. This map should clarify the situation Australia on top

The GreatScott link I have in my post works for me. I'll try again tho GreatScott Guy

Hi Will. You are my go for solar. I've learnt more from you in the last few years than in my 60 something years. Thank you. The only solar I have is 2.4KW grid feed in system. In Queensland the solar/grid system is highly controlled by the state government. Still hope springs eternal. I have a...

Following the above advice. My main concern is, are my maths correct? Using 4-24v 250W solar panels Voc 37.9V Isc 8.65A These are my results 1) Series connect: 151.6V 8.65A Voltage too high for Victron MPPT 2) Parallel connect: 37.9V 34.9A Too large a wire size required 3) 2S2P connect: 75.8V...

H guess you wouldn't be happy with the Redesigned Version? Have you asked Dacian about repairing yours ?

I may be out of my depth. In Australia (240v) this unit is available Plasmatronics. The manuals etc are available to download Guy

I thought this may be of interest. Lithium Australia has some patents on new technology. Somewhere in the forum I had read about DLG batteries Lithium Australia DLG

Solar panels 4-24V 250W in parallel Victron SmartSolar MPPT 100/50 LiFePO4 battery (8x120A) As per Will's DIY LiFePO4 instructions I have read Will's book (thank you Will) and watched the videos several times. 1) I have read/seen somewhere "LiFePO4 batteries do not require a float when fully...

gnubie could you post the link please

I might be wrong, but 8S is a 24V battery not 12V

Dacian's Google group discussing this unit Electodacus

Thank you gnubie Is there some where I can calculate the wire size from the panel to the MPPT, or just base the wire size on using 24V sizes

I'm on the Sunshine Coast. If money is no object totally12volt. I have not used them but they use quality parts. Battery world also sell Enerdrive

Thank you svetv. I'll will look for low Pmax panels. I agree the fridge idea is not my finest hour, back to the drawing board. As regards the breaker from panels to the MPPT this may be the solution Breaker

I haven't been to this shop to check quality etc, tho it may be worth a look. The wire prices seem a bit on the cheap side? I don't know there shipping costs either Big Wei Battery

Thank you. I used the Renogy site

Hi Newenough I watched this video this morning which I thought was very interesting GreatScott. He is in Germany, I assume the BMS and their other components could be posted world wide. This equates to $220.00 Australian for the BMS, very expensive but the unit itself may be what your looking for

Would you recommend these for a newbie and could you post the link to these please

Thank you gnubie and chi. I was off to a bad start, back to the spreadsheet to get the correct panel configuration. I've used the Vmp and Imp, when I should use Voc and Isc
