DESIGN YOUR POWER. BALANCE CONFIDENTLY.

Engineered for Installers

RV Solar + Battery Designer provides professional installers with a high-fidelity engineering tool to assess existing power systems, model proposed upgrades, and design custom solutions ground-up. Transition from guesswork to technical certainty—answering critical questions regarding battery longevity, solar recovery, DC-DC sizing, and system performance during consecutive low-solar days.

Stop Guessing Why the System Is Struggling

When customers present with symptoms like flat batteries, poor solar recovery, or inadequate DC-DC charging, providing a solution requires more than just adding hardware. Identify the root cause through data-driven analysis.

Show the Customer What Is Happening

Before Diagnosis

"You need another battery."

After Designer Analysis

"After three low-solar days, your yield drops and you fall below reserve capacity. By increasing solar and charging efficiency, we maintain a 30% safety margin in poor weather."

Turn cryptic technical values into a compelling visual narrative. By simulating a 7-day journey, you can show exactly when and why the system fails, creating a shared understanding of the problem.

Upgrade What Actually Needs Upgrading

Avoid replacing components unnecessarily. The tool helps identify the most sensible combination of upgrades to fix the problem without excessive hardware cost.

Solar Enhancement

Additional panel capacity to improve recovery speed.

Battery Expansion

Larger storage bank for extended autonomy.

Charge Logic

Larger DC-DC charging to harvest energy while driving.

Inverter / Load

Upgraded inverter capacity and load management.

Test the Proposed Upgrade Before You Install It

"Don’t Just Size It. Test It."

Designers can model the upgraded system before purchasing hardware. Emphasise reducing risk by simulating the real energy performance under intended customer behavior.

Confirm expected battery autonomy
Test several poor-weather days
Confirm DC-DC contribution while driving
Check whether heavy loads are realistic

Design Custom Builds from the Ground Up

For campervan conversions and custom Electrical fitouts, use the same workflow to design around intended travel style, alternator charging, and solar potential before a single wire is run.

Give the Customer a Digital Model of Their System

Provide a locked copy of the final model that reflects the system fitted. The customer leaves with a transparent record of how their system is designed to perform.

For the Customer

Clear Record & Reference
Better Trip Planning
Insight into Load Impact

For the Installer

Professional Handover
Reliable Design Record
Reinforces Design Intent

Turn Technical Problems into Clear Decisions
