Overview
RS-485 Surge Protection Device for three phase inverters with SetApp configuration from 12.5 - 27.6 kW Protects two RS485 buses from electrical surges, such as lightning Easy connection to each RS485 terminal block in the inverter Can easily be added to existing installations without having to redo the RS485 wiring Note: SolarEdge Synergy three phase inverters do not require this since it has been pre-installed in the primary unit and protects the RS485/1.

Reading the specifications
SolarEdge RS485 SPD Plug In for Three Phase Inverters is listed with 1 published specification from SolarEdge, including weight (kg) of 0.2. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.
For an inverter, the figures that matter most are the MPPT voltage window, which decides how many panels go in a string, peak and weighted (European/CEC) efficiency, typically 96–98.5%, topology — on-grid, off-grid, hybrid or micro and continuous AC output in kW, which caps the load you can run at once. It is the component that decides what a solar system can do: how much power you can draw at once, whether you can export to the grid, whether the system keeps running in a blackout, and how well the panels and battery are managed day to day.
What to check before ordering
The checks below apply to any inverter. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.
- Size the inverter against the loads you need to run simultaneously, not against the total wattage of every appliance in the building — a 5 kW inverter comfortably runs a fridge, fans, lights and a couple of ACs, but not all of them plus a water pump starting at the same time.
- Keep the panel array between roughly 1.0 and 1.3 times the inverter's rating. Slight oversizing (a higher DC-to-AC ratio) captures more energy on cloudy mornings and winter days; going far beyond it wastes generation through clipping.
- Check the surge rating if you run motors — deep-well pumps, compressors and older air conditioners can draw two to three times their running current for a few seconds at start-up.
- Choose a hybrid inverter if a battery is in your plan now or later; retrofitting storage onto a pure grid-tie inverter usually means buying a second unit or an AC-coupled battery system.
Where buyers lose money
- Ignoring the ambient temperature rating. Inverters derate in heat, so a unit rated 5 kW at 25 °C may deliver noticeably less on a hot roof-adjacent wall at 45 °C.
- Assuming any grid-tie inverter keeps the lights on during an outage. Standard on-grid units shut down for safety unless they have a dedicated backup or islanding output.
- Overlooking the IP rating. An outdoor installation needs at least IP65; indoor-rated units mounted outside fail early.
Price and availability in United Kingdom
SolarEdge RS485 SPD Plug In for Three Phase Inverters is listed at £ 41 (GBP) for United Kingdom. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.
SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in United Kingdom: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports SolarEdge locally before ordering.
SolarEdge RS485 SPD Plug In for Three Phase Inverters — frequently asked questions
How much does SolarEdge RS485 SPD Plug In for Three Phase Inverters cost?
SolarEdge RS485 SPD Plug In for Three Phase Inverters is listed at £ 41 (GBP) for United Kingdom. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.
What are the specifications of SolarEdge RS485 SPD Plug In for Three Phase Inverters?
We hold 1 published specification for this inverter, including weight (kg) 0.2. The full table is on this page, listed under model SE-RS485-SPD3-B-K3.
Who makes SolarEdge RS485 SPD Plug In for Three Phase Inverters?
SolarEdge RS485 SPD Plug In for Three Phase Inverters is a SolarEdge product, listed under inverters with model reference SE-RS485-SPD3-B-K3. The SolarEdge brand page lists the rest of its range so you can compare across the catalogue.
Is SolarEdge RS485 SPD Plug In for Three Phase Inverters right for my system?
That depends on what it has to connect to. For an inverter, check the MPPT voltage window, which decides how many panels go in a string, peak and weighted (European/CEC) efficiency, typically 96–98.5% and topology — on-grid, off-grid, hybrid or micro against the rest of your equipment before price enters the decision. Match the battery communication protocol (CAN bus or RS485) between inverter and battery. Compatible voltages are not enough; without a supported protocol the battery management system and inverter cannot agree on charge limits.
Where can I buy SolarEdge RS485 SPD Plug In for Three Phase Inverters in United Kingdom?
SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in United Kingdom — buying in-channel is what keeps the manufacturer's warranty valid.
