I am building an RV electrical system and using a Hybrid mini split A/C 12k btu, my RV has a 96VDC 280A battery bank, can I use it to power the DC input of the A/C directly? I don't want to use an inverter because it is quite noisy. Thanks.

This isn’t possible; you would need solar panels for this. You could use batteries through the inverter.

✔ 1. Inverter / Hybrid Compatible AC Chahiye

Hybrid or inverter-type mini split A/C low power par bhi chal sakta hai — isliye battery ke sath zyada compatible hota hai.

✔ 2. Battery Bank Ka Size

A/C bohat power leta hai (600W–1800W tak).
Isliye battery bank bada chahiye, jaise:

  • Lithium batteries (LiFePO₄) – best, long life, fast charging

  • 100Ah lead-acid batteries se bhi chala sakte ho, lekin backup kam hoga

✔ 3. Inverter / Solar Inverter Chahiye

Battery ko A/C se connect karne ke liye aapko:

  • Pure sine wave inverter

  • Ya solar hybrid inverter

chahiye jo A/C ka startup load handle kar sake (2–3× surge).

✔ 4. Backup Time

Example:
1-ton inverter AC ≈ 800–1200W
Agar aapke paas 24V / 200Ah lithium battery ho to approx 2–3 hours backup mil sakta hai.

✔ 5. Solar + Battery = Best

Hybrid mini split A/C ka ideal setup:

  • Solar panels

  • MPPT solar inverter

  • Lithium battery

  • Grid/utility as backup (optional)
