They claim to be maintenance free sealed lead acid batteries. But yes I am planning to find some trays for them as they are inside. I have not found battery boxes that would fit even the smaller 100ah units.KILROY wrote:Looks like those are outside, hopefully. If not make sure you vent them. Those batteries build up enough gas to vent and you will have a problem on your hands if you have them enclosed.
EDIT: Suggest adding some battery trays under each battery, or one big one tray. Just in case they start to leak acid and go bad. The acid will destroy the foundation they are sitting on.
I bought the 2x100ah set for 400aud
the 2x120ah for roughly $460aud
the 2x200ah for 840aud
The Morning Star Mppt 45Amp controller was from USA for AU $529.42AUD
I got 5 solar panels for free while having to pay $400 for the other 4. 1 is in storage but I'm planning to do a smaller circuit with it.
Ive been through 2 Powertech inverters that have failed within months of purchasing; luckily under warranty. ~300aud each.
The Cotek Inverter was a good buy at $263.61AUD + 142AUD Postage from USA. It can even start/run my portable 950W Aircon.
Don't cheap out on the MPPT Controller, I bought one from eBay under 200aud that caught on fire. If I were not home I would've lost it.
All up I probably spent under just 3k if you factor in cabling and mistakes Ive made along the way. 40 Meters of twin 6mm2 cable was $174 alone. Honestly if we owned a house id just get some guys to install a 5kw system for 6k.
I've been learning along the way, id probably be able to spend less.
Not sure if a Grid Tie Inverter actually works but as Storage technology is ridiculously expensive at the moment its probably the best way of going about it.
Its 42Cents a KW on peak hour here so renewable energy is the way to go.
