To get electricity to a horse stable without a grid connection, use solar panels and a battery, with a generator only as back-up where needed. An off-grid system sized on your winter evenings and your biggest machine does the job. A riding school or equestrian centre on a weak connection often does better with semi-off-grid.
You bought a meadow with a stable at the end of a field track. Or your riding school cable is too weak for the arena lights. The grid operator quotes a long cable, so a generator runs every evening.
A stable and cottage in Kasterlee lie very far from the public grid and run this way, with no connection at all.
What does a horse stable use electricity for?
Mostly lighting, water and the fence, and in bigger yards a few heavy machines. The small loads run for many hours. The heavy ones run for an hour, but they set the power the system must deliver.
| Load | Typical power | When it runs |
|---|---|---|
| Electric fence energiser | Small; mains, battery and solar models exist | Day and night |
| Stable and aisle lighting (LED) | Low per fitting; many hours in winter | Mornings and evenings, long in winter |
| Heated drinker | 30 to 80 W per bowl (24 V, with transformer and thermostat) | Frost days |
| Horse walker | Motor of 0.75 kW (4 horses) | An hour or two a day |
| Arena floodlights (LED) | 100 to 150 W per floodlight, often on 4 masts | Winter evenings |
| Hay steamer | 1.5 to 2.75 kW | About an hour per cycle |
| Horse solarium | 2.65 kW (230 V, 16 A) to 5.3 kW (400 V, 25 A) | After riding or washing |
The fence is the easy one. According to Gallagher, mains, battery and solar energisers all suit horses; the choice depends on the fence and what is nearby. The solarium and the steamer need more power than everything else together: they decide how big the inverter must be.
Watch out
Lighting hours add up. A lighting supplier advises at least 150 lux for 16 hours, followed by 8 hours of darkness, in the stalls. In December most of those 16 hours are dark outside.
How much power does a riding school or equestrian centre need?
A riding school needs much more than a private stable, and its peaks come at the same time. The evening lesson switches on the arena lights. The riders then want the solarium, hot water and the canteen.
A private stable with a few horses mostly needs energy (kWh) spread over the day. A riding school also needs power (kW): many loads at the same moment. A solarium on 400 V and 25 A already asks for a three-phase supply on its own.
A competition brings trailers, a sound system, a food stand and extra lights for one or two days. Sizing the whole system on that day is expensive; a generator for those days is more sensible.
Riding school on a connection that is too weak? Read what to do when a 3x230 V connection is too weak. A semi-off-grid system keeps the grid as a charger and lets the battery deliver the peaks.
Why is winter the hard part for a stable without a grid connection?
Because the stable uses the most when the panels give the least. Horses come in earlier, the lights burn longer and the drinkers must not freeze, while the days are short and grey.

A winter day at a stable without a grid connection (illustrative)
Size the system on the summer and the lights, and it fails in January. On a Belgian building forum, a horse owner asked about a meadow where a grid connection was not possible. Lights and fence were no problem; the water pump and a heating wire for the pipes were another story in winter.
The cheapest kWh is the one you never use. Before you add panels, insulate the pipes and choose frost-free drinkers with a thermostat that heats only on frost days.
Tip
Put the panels at a steep angle. A steeper tilt catches more of the low winter sun, even if it costs a little in summer.
Cable, generator or off-grid system: what is best for a remote stable?
It depends on the distance, on what you run and on how often you are there. Each option has a clear place:
| Option | Best for | Weak point |
|---|---|---|
| Grid extension (cable) | Short distance, heavy daily use | Often expensive far from the street; waiting time |
| Generator only | A few hours of work now and then | Fuel, noise, maintenance; someone must start it |
| Solar energiser or small kit | A meadow shelter with a fence and a lamp | No power for a pump, steamer or solarium |
| Off-grid system (solar, battery, generator as back-up) | A stable or yard far from the grid, used daily or at weekends | Must be sized on winter and on the biggest machine |
| Semi-off-grid (weak grid as charger) | A riding school on a connection that is too weak | Still needs a grid connection |
The Belgian cable costs are in whether a battery is cheaper than a grid extension. Already running a generator? Read how a generator and a battery share the work.
Our verdict
Far from the grid, with daily or weekend use, an off-grid system with a small generator as back-up is usually the most reliable choice. The generator only starts in the darkest weeks or on event days.
Off-grid is the wrong choice when the grid is close and cheap:
- Short cable, reasonable quote: take the connection and add a battery later if peaks become a problem.
- A large centre with heavy daily use and a strong connection nearby: grid plus solar and a battery behind it is simpler.
- Electric heating of water or the stable all winter: winter sun cannot fill that need; look at other heat sources first.

How big should the battery and inverter be for a stable?
Size the inverter on your biggest machine and the battery on a winter evening.
What is the biggest machine that must run?
A solarium of 5.3 kW alone is more than a 5 kVA inverter delivers. Decide whether it runs on the system, on a generator, or not at all.
What runs at the same time?
Arena lights, solarium and hot water after the evening lesson add up. The inverter power (kVA: how much it can deliver at one moment) must cover that sum.
How many kWh do you use after sunset in December?
Four arena floodlights of 150 W for 3 hours use 1.8 kWh. A steamer of 2 kW for an hour uses 2 kWh. Two drinkers of 80 W heating all day use up to 3.8 kWh.
How many grey days in a row must the battery bridge?
More days means a bigger battery or a generator. For most stables, the generator is the cheaper answer to the last few days.
Two of our projects show the range. The stable and cottage in Kasterlee make their own electricity all year on 5 kVA of inverter power and 16 kWh of battery. The owner wanted no generator running all the time during stays: the panels cover most use, the surplus charges the battery.
A farm in St-Georges-sur-Meuse used to run fully on a generator. It now has 30 kVA and 46.2 kWh, with the generator only as back-up. A yard with a solarium and an arena sits closer to this one.
Our article on the parts of an off-grid system explains each component.

Can a riding school or off-grid horse barn run fully off-grid?
Yes, with a generator as back-up for the darkest weeks and for events. Fully off-grid without any back-up only suits a stable with modest, predictable use. In St-Georges-sur-Meuse the generator went from running all day to back-up only.
Already on the grid? Then the case changes: a French energy adviser for equestrian centres found that a battery pays back slowly when most activity is in daytime. It pays better when use falls in the evening and morning.
Foaling or security cameras run on the same system or their own small solar kit: see powering lighting and cameras without a grid connection.
Which rules apply to electricity in a stable in Belgium?
A stable without a grid connection is allowed, and the same safety rules apply as with a connection. The main points:
- AREI inspection. The Belgian electrical code (AREI, RGIE in French) applies with or without the grid. An accredited body inspects a new installation before it is used.
- Notification (Flanders). An installation in island mode with an inverter of 800 VA or more is notified to the Vlaamse Nutsregulator.
- Out of reach of horses. A stable builder advises mounting wiring and equipment out of reach of the horses, and keeping hay and straw apart from the stalls.
- Permit. A classic horse stable often needs a permit, and the power supply does not change that: check the zoning and permit with your municipality first.
Battery placement matters too: business battery safety covers fire safety and distances. Building a new stable with no connection at all? Read what to do when a new building has no grid connection.
Watch out
This is general information, not legal advice. Rules in Wallonia and Brussels differ: ask ORES, RESA or Sibelga and the regional regulator.
Frequently asked questions
Can the electric fence run on the same system?
Yes, if the stable is close to the fence: a mains energiser then runs on the off-grid system. For a far paddock a separate solar or battery energiser is often simpler, as Gallagher also advises.
Can a horse solarium run on solar power and a battery?
Yes, if the inverter is sized for it. A 2.65 kW model on 230 V fits a mid-sized system; a 5.3 kW model on 400 V needs three-phase. In winter the energy mostly comes from the battery or the generator.
Can a battery make the generator start only when needed?
Yes. Your generator becomes the back-up: a Victron GX controller starts it when the battery runs low and stops it again. Nobody walks to the shed on a January evening.
Can an off-grid stable be expanded or connected to the grid later?
Yes. Our off-grid systems are always made to measure, can be extended later and can be connected to the public grid, for example as semi-off-grid.
Want reliable power for your stable or riding school?
We start with what you run and when, not with a list of panels. An engineer tells you what size fits and whether a generator stays as back-up.
- Step 1: Tell us your loads. Name the machines, the number of horses and how often the site is used; where possible, we measure real use and peaks first.
- Step 2: Design. Our engineering office calculates the panels, inverter power, battery and, where needed, the generator.
- Step 3: Installation. We install, test and commission the system.
- Step 4: Follow-up. The app and the VRM portal show production, battery and use, with a low-battery alert.
For a weak existing connection, the semi-off-grid route with a generator is what we did for a hunting lodge in the woods at Gedinne.
