Absolutely stellar service from Cameron at Solar 4 RVs. Initially had him quote up a solar system for my campervan back in June 2024 and then when I was ready to purchase in November 2024 he was able to give me the best prices for every product and so I went ahead with the order.
Also gave me some tips to commission the system once I installed the products. Stoked on the Victron gear. Thanks guys!
Purchased a 12v/15a battery charger in 2023. Had issues with it today (2025). Called their info number and explained. Instantly agreed to accept it as a warranty issue and dispatched a replacement without any problems. Extremely quick service and item dispatched express courier that same day. Outstanding customer service. Thank you.
Purchased a literal boat load of electronics from them for our vessel. It all works great and they did an amazing job setting up the panel. We have had the gear a few years now and still reach out when we need help. Great customer service!

Voltage Boosting MPPT
Most solar charge controllers flow energy from a higher voltage panel to a lower voltage battery bank. The GVB series essentially pumps electricity up hill! This series can take a standard 12V solar panel and boost the voltage to charge a 24V, 36V or 48V battery pack.
Before you choose
Genasun MPPT questions
Confirm buck or boost operation, input voltage, output current, battery profile, load features and environmental rating by model.
How do I choose the right Genasun product?
Start with the job the product must do, then compare voltage, current, capacity, dimensions, interfaces and environmental limits for each model. Use the current product page and manufacturer documentation for final selection.
Will Genasun products work with my existing system?
Compatibility depends on the exact model and surrounding equipment. Confirm system voltage, connector or communications standards, charge or load limits, physical fit and every required companion component.
What installation details should I check before ordering?
Check mounting orientation, clearances, cable routes, conductor and terminal sizes, protection, ventilation, environmental exposure, service access and any work that requires an appropriately qualified installer.
Where should I confirm the final technical specifications?
Use the exact product page, current datasheet, installation manual and any model-specific certificates or compatibility lists. Do not rely on another product in the same family because ratings and inclusions can differ.
Do all Genasun products have the same warranty?
No. Warranty periods, exclusions and claim requirements can vary by product family and application. Check the current warranty information for the exact product before purchase.
Can Solar 4 RVs check the complete combination?
Yes. Share the application, system voltage, existing equipment, maximum loads, charging sources, available space and the products being considered. The team can help identify the specifications and companion parts that need checking.
