Lighting, fan, router, laptop, small fridge
LITHVOLT ACADEMY GUIDE
RV and camper power
RV body size alone does not determine the battery. Appliance list, simultaneous load, air conditioning, roof area and alternator capability matter more.
Towable / medium RV
2.5–5.1 kWh · 2–3 kW · 400–800 W
Daily essentials, microwave in short bursts, coffee maker
Large motorhome
5.1–10.2 kWh · 3–5 kW · 800–1,600 W
Multiple appliances and limited air-conditioning runtime
Long-stay / high load
10–20 kWh+ · 5–8 kW · 1–2 kW+
Extended off-grid use; requires a full thermal and charging study
Non-negotiable design checks
Energy
Wh = watts × hours. Battery nominal Wh = volts × amp-hours.
Runtime
hours ≈ nominal Wh × usable depth × efficiency ÷ load W.
DC current
amps ≈ AC watts ÷ (battery volts × inverter efficiency). Higher system voltage reduces current.
Solar yield
daily Wh ≈ array W × peak-sun-hours × 0.75. Use site-specific data for final design.
Educational planning guidance—not a final electrical design, compliance declaration or installation instruction. Local rules and exact manufacturer data take precedence.
