Tiny House lithium banks — duty cycle before brochure cycle life
Tiny House is a duty cycle, not a keyword. Tiny house power solutions. If that sentence is still true after you delete the words “military-grade,” we can quote it.

UN38.3 transport docs on request. DUNS 109774429. We do not publish a star rating we cannot source.
This rail: Residential solar, telecom, warehouse trucks
Typical size: Typical 100–600Ah; parallel for autonomy
What actually fails
- Whole-home backup fails when the bank is sized for lights and someone starts the well pump.
- Garage heat in July is a charge-current problem. Packs need airflow, not a sealed closet.
How we quote it
- List critical loads first. Everything else is a generator or a bigger bank.
- 48V keeps cable and inverter losses in a range electricians will sign off on.

Default house and telecom rail once you are past a few kilowatts. Inverter protocol has to match.
If you delete the voltage, the Tiny House constraints above should still make sense. That is the point.
How we quote Tiny House work
Tiny house power solutions If the house has a hybrid inverter already, we match that protocol. Swapping inverters to chase a cell brand is usually the expensive path. Voltage overlay on this URL is only there because the equipment rail is real — delete the voltage and the duty-cycle advice should still read as a sentence.

Questions we actually get
How do I size a Tiny House lithium bank?
Start from the load you cannot lose. Everything else is optional capacity. We will convert that into Ah at the voltage you already have.
Can I keep my existing charger?
If it can hold a lithium charge curve (higher absorb, little or no float), maybe. Send the charger model. A lead-acid-only charger is how people cook packs.
What paperwork can you send?
UN38.3 is the usual transport packet. CAGE 93CZ2 and DUNS 109774429 for government bids. Other marks depend on the SKU — we send PDFs we actually have.
