Renogy 200mm Water Tank Sender Probe (7.5m Lead, 5-Pin)

Renogy 200mm Water Tank Sender Probe (7.5m Lead)

A 200mm Renogy water tank level sender with a 7.5-metre lead and five-pin connector, purpose-built for the water level inputs on the Renogy Smart Distribution Box PMS1280. Fitted into a fresh water, grey water, or auxiliary tank and wired back to the distribution box, it reports an actual level reading on your Renogy display and in the app — right next to state of charge and solar yield. Stop guessing, stop carrying water you don’t need, and get an early warning long before the pump starts cavitating.

Real Tank Levels in the Renogy Ecosystem

Water discipline is what separates a good bush camp from a short one — the question is never whether the fridge is cold, but how many days of water you have left. This sender gives you a true reading on Renogy ONE displays and in the app, alongside battery state of charge, solar, and loads, so you always know exactly where you stand.

7.5-Metre Lead — One Clean Run

Tanks are almost never near the distribution box — they’re slung under the floor, in the nose cone, or at the far end of a double-axle chassis. A short lead means joins, and joins in a chassis-mounted sensor circuit are exactly where trouble starts. At 7.5 metres, this lead reaches almost anywhere on a caravan or off-road trailer in one unbroken run.

Monitor Several Tanks Independently

The Smart Distribution Box carries four water level circuits, so you can fit a sender to each tank — fresh, grey, and auxiliary — and monitor them all separately from one screen. Ideal for builders adding a second or third tank.

Purpose-Built for Mobile Use

This is an RV-specific sender designed for the water level ports on the Renogy Smart Distribution Box — not a repurposed industrial sensor — so it behaves predictably on a real caravan or trailer chassis.

Ideal For

• Off-road caravan and camper owners running a Renogy Smart Distribution Box who want real tank levels
• Long-range bush campers rationing water accurately in the Kalahari, Karoo, or Namibia
• Builders fitting a second or third tank and wanting each one monitored separately
• Owners replacing a failed or short-lead sender on an existing installation
• Anyone tired of guessing tank level by knocking on the side of it

Important Compatibility Note

Water level senders are not universal. Probe length must suit your tank depth, and the sender type must match what your gauge or controller expects. This is the five-pin, 200mm Renogy sender intended for the Renogy Smart Distribution Box water level ports — if you’re running a different brand of gauge, confirm compatibility before ordering. Tank fittings, sealing gaskets, and mounting hardware vary by tank and are not assumed to be included; confirm the current packing list before ordering if that matters to your install.

Know exactly how much water you have left with the Renogy 200mm Water Tank Sender Probe — an RV-specific tank level sensor that feeds straight into your Renogy Smart Distribution Box and monitoring app for caravans, campers, and off-road trailers.
