Component setup/assembly

[robstrom]

Suggestion/critique welcomed.
3 years after my new cargo trailer purchase/project, ( 7 x 16) it's time for solar.

The plan, subject to change:
-2 (possibly expandable subject to roof space) x 390 watt Hanwha G7, +-6 amp/32 volt.
-Epever Tracer 4215 BN ( love the aluminum body/heat sink effect) 40 amp.
- Battleborn 100 Ah 12 volt
- 300 watt pure sinewave inverter, for a small 3.3 cubic foot fridge/freezer as required.
- Basic 12 volt fuse panel for lighting, some small battery charging, Maxxdome

Have a Honda 2000 inverter gen/27 amp charger when I need it.

My logic:
Given the short wire runs/shading issues/low demand, parallel seems practical.
Location: 54 North!! Talking 60 degree tilt, in July. Winter, have to hang them on the wall.
These are flat, maybe slight tilt for rain/snow etc.
I think here, my roof space is virtually impossible to overpanel.

Q 1: Standard MC4 connector at 10 gauge will work for parallel?
Q 2: Will the 40 amp suffice, given my location?
Q 3: Can the BN roll with LifePo4?

If I understand your questions:
A1: yes
A2: yes
A3: BN has 'User" programmable battery mode; read manual.

Near as I can tell, the 4215 BN is on it's way out, to be replaced by the plastic bodies AN.
BN in Canada about $100 more.
Would you still buy it??
That front facing heat sink seems better than the rear against the wall.
More robust, at a higher price point of course.
Thoughts??

Yes, i have battleborns hooked up to mine, you will set them up in user defined settings.

I have 3 bns, they are a beast. I hope they never discontinue them.

Tell me if I'm seeing a flaw in my planning.
Small inverter to run fridge only, nothing else AC, ever.
The inverter will give the extra 2xish to start the fridge.
I'll buy the fridge n kil a watt it for legit draw.
Will a single Battleborn 100Ah feed that inverter enough AC?
2 batts (costwise) for a small fridge used periodically, is impractical.
I have a small gen to work around the $1,300 extra battery.

Something like that 3.3 cubic foot fridge/freezer uses about 220kWh in a year or 610 Watt-hours per day.

I would say you need more battery Amp-hours.
It seems you already have one lithium style battery, correct? Pricey.

If not, buy 3 100 Ah SigmasTek AGM batteries SP12-100 IT for $450.

SigmasTek SP12-100 IT Battery

SigmasTek SP12-100 IT battery replacement - get a 12V 100AH SLA Battery. Guaranteed compatibility with the original SigmasTek SP12-100 IT battery.

By the time the SP12-100 IT die the "Battle-born" battery technology will be obsolete.
In the mean time you've got $2000 extra cash to enjoy life.

I have 2 systems. 1 system 1000 watts in panels, 40 amp epever, 4000 watt inverter, 4 battleborn batteries. Started with 2 batteries on first system, ran full size fridge, microwave, family room with lighting and ceiling fan an DC master bathroom. As long as sun was out every day, everything was fine. Full size fridge pulls about 1.4 kw per day.

Kill a watt will show continuous current draw and watt-hours. But it won't show starting surge. Assume 5x label rating.

Batteries? I assume PV is involved. Power fridge during daylight only. Now battery only has to supply starting surge (e.g. 2000W or so for a full size) for about a second. And fill in hours of the day with less sun. But not run at night. Generator can take care of inclement weather.

I would orient two parallel-wired PV panels for morning and afternoon sun.
