complete build, good setup? questions
hey I have done lots of reading and phone calls, and decided to go with viltron Lifepo4 batteries if I can get a bulk deal on them. also, if the 15% off coupon I have is still valid. if not, I w...

Mako Kupa I was working off line before your recent post and don't want to redo that respone (no wasting the grey matter);)
First let me say this was installed not be me but I think I could do it now. I'm by no means an expert (many smarter/ knowledgeable on the forum) other than I know how my system works in different environment conditions and pretty much the components installed for the system. It was built from scratch (clean slate) there was no trying to repurpose prior components but built to make larger for the day when it gets parked and like you I'll transfer most of this to a cabin (24v or 48v system instead).
These batteries are not drop in style. The cpu and misc components are housed in a plywood box the cover was removed for the picture. This is just a larger "control center" or part of the "BMS". The prismatic cells allow for higher charging/ discharging current.
-Max Charging Current: 3C (300 Amps)
- Max Discharge Current: 3C (continuous) / 10C (pulsed)
Drop in batteries have their "BMS" built into the battery box with either pouch style or cylinder style Lifepo4 a neat already assembled battry package. The limits for charging/ discharging are lower though and differ from manufacturers which is something that should be thought about depending on what might be run at one time. The inverter will also limit that though.
Obviously prices differ from mfgs and size of battery bank.
500ah GBS is roughly $4,200 end user has to assemble. Something in the size you mentioned earlier in the post of 800ah (4-200ah batteries) $7,000.
Where as Battleborn 800ah would be $7,600 but just add cables. Other mfgs seem to be near the same price range.
There is always the debate of which controller is better mppt or pwm. All the variables have to be looked at voltage, parallel, series possible shading and just size of solar array. Let's not forget $$$$.
I personally went Magnum because the inverter/charger & controller played well with each other meaning that in the me-arc theres a setting for linking them so no messing with dip switches in the pt controller it follows the inverter/ charger settings which work great for my Lifepo4 batteries and down the road if I felt like tweeking the charge setting it's simple.
I'm sure Victron, Morningstar and others have similar I've haven't done any deep research on those but seem like end users that have other brands are just as happy.
Bluetooth, wifi gadgets are cool but after awhile the display is just something thats there and the "novelty" wheres off. Once your system is up and running properly what's to look at other than daily production at the moment or recorded highs/ lows.
