Want more capacity without lugging large, heavier batteries into your limited space? Firefly uses the same carbon fiber technology in a 4v size (each battery is 450 Ah!) - perfect for that unique space, off-grid applications, RVs. Get all the info here: Firefly 4v Batteries.
Marine Cooling, Refrigeration, Monitoring, and Solar Solutions
Are you a boat owner, or soon-to-be boat owner, with questions about your vessel's systems? Let us help you find those answers. For example:
- How many amp/hours are your solar panels putting into your battery bank? Philippi's PSM System Monitor will tell you.
- Water-cooled vs air-cooled refrigeration, see "Which Condensing unit should I use" in Refrigeration > Planning.
- Planning for solar panels on our boat? See "Marine Solar Panels Planning and Installation Guide in Solar > Planning.
- Air-conditioning on your boat, while on the hook and no generator running? (Yes you can!)
- Need a refrigerator or freezer cabinet for a small space? See our catalog - Vitrifrigo has many sizes to choose from
