So will be doing some upgrades and moving my current system next week.

Here is the plan:

Main system:

3X300W panels on the roof - Connected through a 3 into 1 MC4 connector with a 30 Amp fuse. (Currently only have 2 panels)

4*T105 Trojan Batteries

1X Axpert 3kva 24V Inverter (had for the last 3 years)

DB Board with 220V in and out trip switches, 125A Fuses for the batteries and DC Disconnect for the panels.

1X HA02 Balancer

220V Power will be run to plugs (Not going through main DB Board) and some Sonoff switches used to remotely monitor power usage and switch off high use power items if needed at night [Freezer] if there is a power failure.

 

Light system (Run upstairs 12V Lights that have been installed in my roof - About 12 3-5W Globes in total)

1X120W Panel

1X 60Ah Omnipower battery

1X PWM Charge controller (Had it when i first started and replaced with Axpert)

Fuse on battery and panel - 10 Amp

 

Will post pics once the system back up and running

So i have decided to add another bank of Trojans to this system as well as their own HA02 balancer.

I will also be adding a 4th panel to assist with early morning and late afternoon charging capability. (I was thinking of adding 3 12V panels to up the voltage on the existing 3, but a 4th seems better as if i decide to go 48V in the future, i just need another 2 panels and wire them all in series to meet this need.

 

Anyone have any experience with Suntech panels? (Voltage is the same as my existing, so wont bring the system performance down in the parallel connection.)
