Tailored load balancing
Dynamically matched to the block's actual power capacity rather than a fixed limit.

EV charging for apartment blocks
Charge the whole building on the supply you already have.
An apartment block normally has enough electrical supply for far more chargers than it can install without load balancing. LinkRay measures what the building is actually drawing and shares the remaining capacity across every charge point, so a whole block can charge on the supply already at the site. No grid upgrade, no subscription, and no restriction on which chargers you fit.
It works with any OCPP compliant charger, and with AC and DC units mixed on the same site, so you are not tied to one brand. Authorisation and usage are tracked per charger, so each resident is billed for the power they actually use. And the installation can be monitored and adjusted remotely, which removes most of the reasons for a return visit.
Why the supply becomes the limit
Fit several chargers in an apartment block without load balancing and the building's supply caps the scheme. Peak evening charging risks tripping the feed, which means outages, emergency callouts and unhappy residents. More often it means you simply cannot install the number of charge points the contract calls for, and the contract goes to someone who can.
Taking more power is rarely the answer. The G100 limit on the connection determines what the site may draw, and a network reinforcement often costs more than every charger in the scheme put together. Our site capacity check will tell you how many chargers a given supply will carry.
Billing is the second problem. Without per user authorisation and metering there is no fair way to charge individual residents for the electricity they use, which produces disputes, dissatisfied clients and no referrals.
Why installers use LinkRay
Subscription free
No back office contract and no recurring platform fee.
Universal compatibility
Any OCPP compliant charger, with AC and DC units mixed on the same site.
Per resident billing
Usage tracked per charger, with contactless payment through our payment terminal where visitor charging is wanted.
Remote management
Monitor and adjust from anywhere, which prevents most callouts.
Proof
“So cool. LinkRay is such a versatile product. It is the missing link really for so many multi dwelling unit charging use cases that does not exist anywhere else.”
Our power management case study shows the same approach on a larger site.
Why Versinetic
Our load balancing technology is in use across four continents. There is no minimum order, so a single block is a normal first order, and we can arrange for you to test your own chargers remotely against LinkRay before you commit. If you want to understand how we work with installers first, here is how we work with clients.

Tell us the supply and the charger count
Give us the building's supply and how many charge points the contract needs, and we will tell you whether it works. You will hear back from an engineer, usually within one working day.
FAQs
Frequently asked questions
What is EV charger load balancing, and why does an apartment complex need it?
Load balancing means sharing a fixed electricity supply across multiple EV chargers so none of them draw more power than the building's incoming feed can handle. Without it, a full car park charging overnight can trip the supply or force you into an expensive grid upgrade before you're allowed to install more than a couple of points. LinkRay monitors your site's meters in real time and shares out the available power dynamically, so you can fit more chargers into the capacity you already have.
How many EV chargers can I install on one apartment complex supply?
That depends on your incoming supply capacity, not just the number of parking bays. A single LinkRay unit manages load balancing across up to 100 sockets, which covers most apartment blocks. If your site is larger, has multiple meters or transformers, or you're coordinating several LinkRay units across one complex site, SiteManager sits above LinkRay to keep them working together.
Will I still need to notify the DNO if I'm using load balancing?
In most cases, yes. Load balancing manages demand within your existing supply, it doesn't replace the Distribution Network Operator's requirement to be notified about new EV charging infrastructure, particularly for multi-charger commercial or communal sites. What it does is reduce the chance that your DNO comes back asking for a costly supply upgrade, because you're demonstrably managing peak demand rather than adding it uncontrolled. Always confirm current notification requirements with your DNO or a qualified electrical consultant before you finalise a design.
Can I bill individual residents for their own electricity usage?
Yes. LinkRay tracks usage per charger and supports contactless authorisation, so each resident's charging session can be metered and billed separately rather than lumped into a shared service charge. That's usually the difference between a smooth resident experience and a stream of billing disputes landing on the property manager's desk. See our contactless payment terminal integration for how authorisation and billing fit together.
Does LinkRay work with EV chargers from different manufacturers?
Yes. LinkRay integrates with any OCPP-compliant charger, AC or DC, so you're not locked into a single brand. That matters on apartment retrofits especially, where you might be adding chargers to an existing mixed-brand site rather than starting from scratch.
What's the difference between static and dynamic load balancing?
Static load balancing splits a fixed power budget evenly (or by a set ratio) across chargers, whether or not a car is actually plugged in and drawing current. Dynamic load balancing, which is what LinkRay does, continuously reads real demand from your meters and reallocates power as it changes, so a charger with no car connected doesn't hold capacity hostage from one that's actively charging. For most apartment sites with varying resident arrival and departure times, dynamic is the more efficient of the two.
Do I need an ongoing subscription or back-office system to run LinkRay?
No. LinkRay doesn't require an expensive subscription-based back-office platform to manage load balancing on site, which keeps ongoing costs predictable for you and, in turn, for the property owner. If you do want a back-office layer for wider fleet or site management, our EV charging back-office software is available separately, on your terms rather than as a forced bundle.
What if my apartment complex grows beyond one LinkRay's capacity?
You add another LinkRay and coordinate them with SiteManager, our supervisory layer built for exactly this situation. It's designed for a single complex site with multiple meters or transformers, such as a large residential development, not for managing separate sites in different locations. Worth flagging early with your installer if you expect the site to expand in phases, so the electrical design accounts for it from the start.
