Simpson & Partners Dual Freestanding vs Rolec Quantum: Which Commercial EV Charger Is Better?

Most commercial EV charger comparisons focus on unit price. Experienced installers compare total installed cost, time on site, and long-term reliability. That's where the Simpson & Partners Business Pro Dual Freestanding separates itself from the Rolec Quantum and similar pedestal options.

The Core Difference: Integrated vs Pieced-Together

Most commercial pedestal setups require separate components assembled on-site: a charger unit, external RCBO protection, separate metering, additional networking hardware, and often external PME protection devices. Each is a separate purchase, a separate installation step, and a separate potential failure point.

The Simpson & Partners Business Pro Dual Freestanding takes a different approach — everything is engineered as one complete system from day one. Internal cabling, protection, and connectivity are fully integrated before the unit leaves the factory.

Why this matters for commercial projectsA 10-charger car park with piecemeal systems involves 10× the complexity. With integrated units, the installer's job is consistent and predictable — which translates directly into cost savings and fewer callbacks.

Side-by-Side Comparison

Feature	Simpson & Partners Dual	Rolec Quantum / Typical Pedestal
Dual sockets	Yes — standard	Often single socket only
RCBO built-in	Yes — per socket	External RCBO required
PME / PEN protection	Integrated	External device required
Load management	Built-in dynamic load balancing	External system required
OCPP support	Yes — open platform	Limited / proprietary
Network connectivity	WiFi + Ethernet	WiFi only (typical)
Metering	Built-in kWh metering	External meter often required
Multi-charger scaling	OCPP backend + DLM	Complex — external systems needed
Billing capability	OCPP billing-ready	Separate system required
Warranty	Up to 10 years	Typically 2–3 years
Total installed cost	Lower — fewer add-ons	Higher when all components included

📖 Plain English

When you price up a Rolec Quantum for a real car park project, you have to add: RCBO protection box, PME device, kWh meter, networking hardware, load management system. By the time you've bought all of that and paid for the labour to install it, the Simpson & Partners unit — which includes all of this — often works out cheaper overall. And it's all under one warranty.

Where Simpson & Partners Wins on Commercial Projects

⚡

Two Chargers, One Install

Dual sockets mean two vehicles charge simultaneously from one supply connection — halving trenching, cabling, and connection costs per parking space.

🔌

No External Protection Box

RCBO and PME protection built in. No separate distribution board or protection device needed in most installations — saves material and labour time.

📊

Built-in Load Management

Dynamic load balancing prevents tripped fuses and costly supply upgrades. Essential for multi-charger sites — and included, not an add-on.

🏢

Scales to Fleet & Multi-Site

OCPP 1.6J+ means any fleet or property management backend can connect — no proprietary lock-in, no vendor dependency.

💷

Lower Total Project Cost

EcoHarmony's volume purchasing on large projects gives highly competitive unit pricing. Less hardware + less labour = genuine cost savings.

🛡️

Up to 10-Year Warranty

Commercial installations need long-term confidence. Rolec typically offers 2–3 years. Simpson & Partners backs the full system for up to a decade.

Real-World Cost Comparison

Cost Element	Rolec Quantum Setup	Simpson & Partners Dual
Charger hardware	£X (single unit)	£X (dual unit — 2× sockets)
External RCBO/protection	Required — additional cost	Built-in — £0 extra
PME device	Often required — additional cost	Integrated — £0 extra
Load management	External system required	Built-in — £0 extra
kWh metering	Separate meter required	Built-in — £0 extra
Install time (extra complexity)	More components = more time	Single system = faster install
Warranty coverage	2–3 years typical	Up to 10 years

The real comparisonDon't compare charger prices. Compare total installed cost including all required ancillary hardware. In most commercial projects, Simpson & Partners delivers a lower total cost — and a significantly better long-term outcome.

When Would You Still Choose a Basic Pedestal?

For a single-charger, single-vehicle installation with no future expansion plans, no billing requirements, and a very tight budget — a basic pedestal with an external charger can still be a functional solution.

But as soon as any of these apply — more than one charger, limited available power, requirement for billing, need for management software, or plans to expand — the Simpson & Partners integrated system becomes the more cost-effective and practical choice.

Frequently Asked Questions

Is the Simpson & Partners Dual Freestanding really cheaper than a Rolec Quantum setup?

In most commercial projects, yes. The Rolec Quantum unit price may be lower, but you need to add external RCBO protection, PME device, kWh metering, and load management. When all components and labour are included, Simpson & Partners typically delivers a lower or comparable total installed cost — with far better warranty and capability.

Does the Simpson & Partners Dual support OCPP billing?

Yes. OCPP 1.6J+ support means it can connect to any compatible fleet management, billing, or energy management backend. This is essential for commercial sites where usage needs to be tracked or charged for.

Can the Simpson & Partners Dual Freestanding handle limited power supplies?

Yes. Built-in dynamic load balancing manages the available power supply intelligently across both sockets — preventing trip events and making it viable for sites where a full 14kW dedicated supply isn't available.

What warranty does the Simpson & Partners Business Pro Dual have?

Up to 10 years on the enclosure. This significantly outperforms the 2–3 year warranty typical of Rolec and similar commercial pedestal options — and matters enormously for a product expected to be in-service for a decade.
