RV Electrical Planning Involves a Lot of Numbers
How much battery capacity do you need?
How much solar? What size inverter? How long will your batteries last? Is your cable run creating too much voltage drop?
Instead of jumping between formulas, spreadsheets and individual online calculators, bring your key RV electrical calculations together in one dedicated planning Toolkit.
17 Essential Calculators. One Powerful Toolkit.
From estimating daily energy requirements to checking cable voltage drop, the Toolkit helps you work through the numbers behind your RV electrical system.

CTA: Explore Your System With 17 Interactive Tools
🔋Understand Your Power & Battery Requirements
Start with the foundation of your electrical system.
Estimate daily consumption, explore battery-bank requirements, calculate approximate runtime and understand how series/parallel battery configurations affect voltage and capacity.
Includes:
- Power Consumption Calculator
- Battery Bank Calculator
- Battery Runtime Calculator
- Watts / Amps / Volts Calculator
- Battery Series / Parallel Calculator
☀️Plan Your Solar Charging System
Move from daily energy requirements to solar generation and charging.
Estimate solar-array requirements, recharge time and MPPT planning values while exploring different panel configurations.
Includes:
- Solar Array Calculator
- Solar Recharge Calculator
- MPPT Controller Calculator
- Solar Series / Parallel Calculator
- PV Cable Calculator
⚡Plan Beyond Solar
Solar is only one part of an RV electrical system.
Estimate inverter requirements, understand the DC current demanded by AC equipment and work through important planning values for alternator/DC-DC charging.
Includes:
- Inverter Calculator
- AC Load → DC Draw
- Inverter Cable Calculator
- DC-DC Charger Calculator
🔌Take the Guesswork Out of Cable Calculations
Cable length, current and voltage drop can dramatically affect a low-voltage electrical system.
Use dedicated tools to explore conductor sizing by voltage drop, calculate expected voltage loss and assist with preliminary circuit-protection planning.
Includes:
- Wire Size by Voltage Drop
- Voltage Drop Calculator
- Fuse / Breaker Planning Calculator
Small safety line:
Wire and protection results are planning aids and must be verified for conductor ampacity, equipment requirements and applicable standards before installation.
🚐 Enter Your System Once. Plan More Efficiently.
Create a basic My RV System profile with important values such as:
- System voltage
- Battery capacity
- Usable battery depth
- Inverter efficiency
- Solar efficiency
The Toolkit can use these values throughout your planning workflow, reducing repetitive data entry.
Don't Just Get a Number. Understand What It Means.
Important calculations include explanatory guidance to help you understand:
- What the result represents
- Which assumptions were used
- What should be checked next
- Which equipment limitations may affect the final decision

Important Safety Information
The RV Solar & Electrical Calculator Toolkit is an educational and planning resource. Calculator outputs are estimates based on the information entered and the assumptions stated within each tool.
It does not constitute an electrical design, installation certification, code-compliance determination or professional engineering advice.
Safety-critical values—including conductor ampacity, fuse/breaker selection, battery/BMS limits, PV limits, grounding/bonding, shore-power wiring and equipment-specific requirements—must be verified against applicable standards, manufacturer documentation and appropriately qualified professional guidance where required.
Never rely solely on a calculator output for a safety-critical installation decision.
Plan Smarter. Calculate With Confidence.
Bring the key numbers behind your RV solar and electrical system together in one dedicated planning Toolkit.
