Hi all,
I'm already off-grid, but using a very underpowered system currently:
I'm looking to upgrade to something that supports home electricity usage as well as an electric kiln.
I'm at the point where I feel I've done a decent enough research where I'd appreciate other eyes:
Current goals/questions:
Thanks for reading and any and all input.
I'm already off-grid, but using a very underpowered system currently:
- Grape Solar PV: 8x185w
- Mighty Max ML100-12 (DS-IGEL): 4x12v100AH
- Backup generator that I use on the regular.
I'm looking to upgrade to something that supports home electricity usage as well as an electric kiln.
- Home electricity usage targets 2kw.
- Electric kiln:
- 13kw rating - 70% duty cycle as it turns on and off as part of the heating process so 9.1kw actual
- Kiln duration targeting 10 hours.
I'm at the point where I feel I've done a decent enough research where I'd appreciate other eyes:
- Signature Solar E000 + 2 additional Battery Racks
- 12kw PV
- 81.9kWh Battery
- 13k Inverter
Current goals/questions:
- Is the PV, Battery, or Inverter too little, too much, or all wrong?
- I aimed at the worst month in southern California and it'd leave me with surplus of 5.9kWh of buffer.
- Requirements: 2kw home + 9.1kw kiln = 11.1kw
- Starting the kiln at 10am PT, assuming batteries are fully charged at this point (2-4 days to charge)
- Requirements for the 10 hour firing = 11.1*10 = 111kWh
- PV Generates 35kWH (per Average Hourly Profile on GlobalSolarAtlas, 10a to 8p in December)
- And 76kWH is taken from the 81.9kWh Battery, leaving 5.9 kWh buffer.
- Walking through this... I see that the 13k Inverter is maxed with a 13kw rating kiln... I think I can adjust the kiln target to being closer to 11kw rating (7.7kw actual) and still meet my needs.
- I realize this isn't the cheapest route, and a gas kiln would reduce cost significantly, but there are quality of life considerations that will make an Electric Kiln still desirable in addition to a gas kiln.
- I aimed at the worst month in southern California and it'd leave me with surplus of 5.9kWh of buffer.
- Can I get a NEMA 6-50p plug connected to the Inverter? Related, can the Inverter support a well pump?
- How far from the Inverter can I put the Electrical panel without "significant" power degradation or could I have the panel close to the Inverter and have the supported AC lines extended? I have 5 acres of multi-tiered boonies, so distance flexibility is good.
- Any questions I should be asking that I'm not? Does any of my info or assumptions seem off?
Thanks for reading and any and all input.
