100kW BNQ4 Synergy Manager DC Safety Switch, MC4, DC SPD
SolarEdge Three Phase with Synergy Technology — 50 kW to 100 kW that two people can carry up a ladder, one Synergy Unit at a time.
A 100 kW inverter is normally a crane job. Synergy Technology takes it apart: one Synergy Manager plus two or three Synergy Units, each light enough for two people, assembled on the wall. On a retrofit roof with no plant room, no lift and no crane access, that is often the only workable answer.

About the SolarEdge Three Phase with Synergy Technology
Splitting the inverter also splits the risk. Each Synergy Unit operates independently, so a fault takes out a third of the capacity rather than all of it, and a failed unit is swapped without dismounting the whole inverter. On an asset with a performance obligation attached, that uptime difference matters more than a tenth of a percent of efficiency.
The pre-commissioning feature validates wiring and system configuration during installation, before grid connection — catching the wiring errors that otherwise surface on commissioning day with the DNO waiting. Thermal sensors watch for faulty terminations, built-in PID mitigation protects long-term yield, and the surge protection devices are monitored and field replaceable.
String design, certification and what is in the box
The details that decide whether this unit suits the job:
- Modular: one Synergy Manager plus two or three Synergy Units. Each piece is a two-person lift.
- Inverter power rating is set at commissioning, so one part number covers several ratings.
- Pre-commissioning validates wiring and configuration before grid connection.
- SafeDC as standard with optional rapid shutdown; arc fault protection built in.
- Built-in PID mitigation; monitored, field-replaceable DC and AC surge protection.
- Optional integrated DC safety switch removes external DC isolators.
- 1,000 Vdc maximum, 680 – 1,000 Vdc operating window.
Where this inverter earns its place
The Three Phase with Synergy Technology is specified most often for these jobs.
Can I add a battery to this?
This is a grid-tied PV inverter. It converts solar DC into AC for the property and the grid, and it has no battery port. That is not a shortcoming — it is the right architecture for a system without storage, and it is why it costs what it does.
If storage is on the roadmap, you have two routes. Add an AC-coupled battery system alongside this inverter later, which works with any PV inverter and needs no change to what is already installed. Or choose a hybrid inverter now and pay for a battery port you will use in a year or two. We are happy to talk that trade-off through before you order.

Questions we get asked about this inverter
What actually arrives on site?
A Synergy Manager and either two or three Synergy Units, depending on the power class. They assemble on the wall into one inverter. Secondary units are also available separately as spares or for expansion.
Why does modularity matter?
Handling and uptime. A 100 kW monolithic inverter needs mechanical lifting; Synergy Units do not. And when one unit faults, the rest keep generating.
What is pre-commissioning?
An automated check of wiring and system configuration performed during installation, before the grid connection is live. It catches wiring faults while the installers are still on site rather than on commissioning day.
Do I need optimisers?
Yes, on every module.
What warranty?
12 years standard, extendable to 20.
Documents, advice and trade pricing
Every datasheet, certificate, installation manual and warranty document we hold for this product is in the Documents tab below. See the rest of our inverter range and our solar panels, or email our sales team at sales@clearraysolar.com if you would like us to check a string design or a compatibility question before you order.
Three figures govern it, all in the Technical Specifications: the MPPT voltage range, the maximum input voltage and the maximum DC power. Tell us which panel you're pairing it with and we'll confirm the string layout.
G98 covers installations up to 3.68kW per phase and is notified to your DNO after commissioning. Anything larger needs G99 approval agreed beforehand. We can flag which one your design falls under.
A hybrid inverter takes a DC-coupled battery directly. A standard string inverter needs an AC-coupled battery alongside it. The Technical Specifications show which type this unit is.
Yes, up to the maximum DC power figure in the specifications. Modest oversizing is normal practice - it lifts output in winter and at either end of the day, at the cost of brief clipping at midday peak.
An MPPT tracks the optimum operating point for a string of panels. You want one per roof orientation or pitch, because panels facing different directions on a single tracker drag each other down.
The standard manufacturer warranty is listed under the Warranty tab. Extended cover is available on most brands - see Warranty Extensions.
