A 30 kW Solar Plant for Business — Turnkey, with Backup for Outages
A solar plant for a shop, a service station, a workshop, a farm or a small production site. In the configuration with storage, your critical equipment keeps running when the grid goes down — within the capacity of the storage. Design, in-house switchgear, installation and grid connection — one company, one contract.
Honestly about the main thing: when a solar plant works during an outage and when it does not
the first substantive block — it is the message match to the ads, and it also removes the market's main misconception
Yes — provided the plant has storage. A hybrid inverter together with battery storage (BESS) separates your site from the lost grid and powers it from the battery and the sun. That is exactly the configuration we build when the task is to keep working during outages.
But an ordinary grid-tie solar plant without storage does not work when the grid goes down. This is not a fault and not a saving on equipment: a grid inverter is obliged to switch off when voltage disappears from the grid (anti-islanding protection, ДСТУ EN 50549-1:2022 / -2:2022 — Ukrainian national standards) so as not to feed current into a de-energised line where a repair crew may be working. So panels on their own "to have light during an outage" do not solve the task.
What this means in practice:
- The backup holds not the whole site, but the critical load — what you have defined in advance: tills and payment terminals, refrigeration equipment, the server and communications, lighting, individual machines or pumps.
- How long it lasts depends on the capacity of the storage and the power of the hybrid inverter, and during the day also on the sun. We calculate this against your list of critical loads, rather than promising "full autonomy".
- Full energy independence from the grid is a different and significantly more expensive task. We say so honestly at the calculation stage.
Three configurations for 30 kW:
| Configuration | What it gives | Works during an outage |
|---|---|---|
| Grid-tie | reduces your daytime electricity purchases from the grid | No |
| Hybrid with storage (BESS) | the same + power for the critical load when the grid is down | Yes — within the battery capacity and the critical load |
| Hybrid + ATS and a backup source | the same + automatic transfer to a backup supply (a generator, among others) | Yes — within the battery capacity, then from the backup source for as long as there is fuel |

Who this suits
A 30–50 kW plant is a format for businesses with daytime consumption and their own roof or plot:
- Retail and HoReCa — a shop, a supermarket, a café: refrigeration, tills, lighting, air conditioning.
- Production and workshops — machine tools, compressors, ventilation.
- Service stations, car washes, warehouses, logistics.
- Agriculture and farms — pumps, dryers, cold rooms.
- Offices and service companies — equipment, servers, communications.
The economics work best where consumption falls within daylight hours: what the plant has generated, you consume on the spot instead of buying it from the grid.

Why LK Energy
1. A switchboard of our own manufacture. The most critical part of a plant is its switchgear. We manufacture switchboards for 0.4–35 kV at our own factory: control over quality and over manufacturing schedules. For a plant with backup this is fundamental — the protection and the ATS live inside the switchboard.
2. A design-and-manufacturing company with its own switchgear factory. Design, relay protection, grid connection — this is our daily work on sites ranging from switchboards to substations. The plant's entire electrical circuit is handled by one engineering team: from the calculation to the connection and servicing.
3. Experience you can see. 6 MW (AC) of industrial solar plants delivered; the flagship is a 4.95 MW plant with storage, delivered in the Odesa region. Plus engineering experience on nuclear sites — the Chornobyl NPP (as a subcontractor) and the Rivne NPP.
What it costs
Indicative turnkey cost of a 30 kW plant:
| Configuration | Price | Works during an outage |
|---|---|---|
| Grid-tie | from $14,000 | No |
| Hybrid, with backup (storage) | from $20,000 | Yes — within the storage capacity, for the critical load |
The exact price comes after a site survey. It depends on:
- Grid-tie or with storage — the storage changes the budget substantially (and it is exactly what gives you operation during outages).
- Roof or ground — the type of roof, its load-bearing capacity, mounts or piles.
- The condition of your electrical installation — what is already in the incoming switchboard, whether a new switchboard and an ATS are needed.
- The equipment — the class of the modules and the inverter.
- The grid connection — whether the generation fits within the site's already permitted capacity.
We provide a calculation for your site with a breakdown by component — you can see what you are paying for.
Prices are indicative and are not a public offer. The exact cost is determined after a site survey. The effect for your site is calculated individually — against your tariff, your consumption profile and the plant's configuration.
How we work
- Enquiry — the capacity or the roof area, the type of site, approximate consumption.
- Survey and consumption profile — what you consume and when.
- Configuration and calculation — capacity, backup (if required), the equipment set, the budget.
- Contract and design.
- Switchboard manufacturing, equipment supply, installation.
- Commissioning and start-up, then monitoring and servicing.
Timelines depend on the configuration and the connection conditions — we give an indicative schedule together with the calculation.
What the work includes
- Survey and calculation — we take your consumption profile, assess the roof or the plot, and calculate the configuration.
- Design — the electrical part, the single-line diagram, the working documentation.
- Equipment — a switchboard of our own manufacture (including with an ATS, if backup is required); photovoltaic modules and inverters — from proven manufacturers.
- Installation — mounting structures, modules, cable routes, earthing, lightning protection.
- Connection and paperwork — the application to the operator for the installation of a generating unit, the single-line diagram, the inspection and sealing, the drawing up of certificates; where required — the connection service and active consumer status, if you plan to export surpluses.
- Commissioning, monitoring, servicing and the warranty.
- One contract and one party responsible for the entire electrical scope — from design to connection and service
