Inverter, power station, generator and solar panel installation
Need an inverter in an apartment, a power station wired into the electrical panel, a generator connected to a house or solar panels on the roof? Describe what has to keep running during outages, and installers will send responses. Or choose one by photos of installed systems and client reviews.
Backup power installers
How much inverter installation costs
What affects the price
Single-phase or three-phase
A three-phase system for a house needs a different inverter, five-core cable and more panel work than a single-phase one in an apartment.
What to back up
To run only the boiler and a few outlets from the inverter, those circuits are moved to a separate group in the panel, while backing up the whole home takes more powerful equipment.
Distances and cable runs
The farther the inverter or generator is from the panel, and the solar panels from the inverter, the more cable, conduit and time it takes.
The roof under the panels
Metal tile, corrugated sheeting and flat roofs need different mounts, while on the ground the panels go on a separate frame.
Switching and protection
An automatic transfer switch costs more than a manual changeover switch, and surge protection and new breakers in the panel add to the cost if you don't have them yet.
Prices come from specialists' profiles on Nexperity and update automatically. You agree the final price with the specialist directly.

How to choose a backup power installer
- 1
Your inverter brand
An installer who has already fitted your inverter brand knows its settings and typical faults. Look in the portfolio for similar systems — in an apartment, with a generator or on a roof.
- 2
Sizing for your appliances
Ask them to calculate the load of the appliances that will run at the same time: the inverter's power and the battery capacity depend on it.
- 3
Switching between sources
Ask how the installer will switch your home between the grid and the generator — a manual or automatic transfer switch: power must never come from two sources at once.
- 4
Roof mounting
For panels on the roof, ask how the installer will fix the frame and what they will seal the roof penetrations with, so the roof does not leak.
- 5
Setup and warranty
Check whether the installer will set up the inverter for your battery type, show you how to use the system, and give a warranty on the installation.
What to put in the order
What needs installing: an inverter with batteries, a power station, a generator, a UPS or solar panels
Apartment or house, single-phase or three-phase — if you know
Which appliances must run on backup power: boiler, fridge, pump, router
Whether the equipment is already bought — make and model of the inverter, power station, generator or panels
Where the equipment can go: a storeroom or balcony for the inverter, a spot outdoors for the generator
For solar panels — the roofing type and the approximate area of the roof or plot
Questions about Nexperity
How Nexperity works — separately for clients and for specialists
For clients
Nothing. Searching for specialists, sending requests, posting orders and receiving responses are free.
No. You agree the price and the payment method with the specialist and pay them directly. Nexperity does not take payments and is not a party to your deal.
A request goes to one specialist — from their profile. An order is posted for everyone: specialists send you responses, and you choose which one to accept.
How the specialist will do the task, a price — fixed, a range, hourly or “on request” — and, optionally, an estimated timeline.
30 days from publication: all that time it is visible in the feed and specialists can send responses. The exact end date and time are shown on the order in your account. From that moment the order is closed and a response can no longer be accepted. You can cancel it earlier, and if no specialist turned up, post a new one.
Yes: you can hide your name and photo in an order. The anonymity lasts until acceptance — the specialist whose response you accept sees your name and photo. The task description is public: anyone visiting the site can read it.
Only after acceptance — when you accept their response or they accept your request. And only the contacts you chose to show.
After acceptance you see the contacts the specialist chose to show, and they see the ones you chose. You can also message on Nexperity when the chat is on: on an order you decide that, on a direct request the specialist does.
Once the work is done, mark the order or the collaboration completed in your account — then you can say whether you recommend the specialist. A review can only be left for a collaboration that happened through Nexperity: one per specialist, which you can change or delete at any time.
For specialists
Nothing for now: this is the free period, and no subscription is needed yet. Nexperity takes no commission on deals — you settle with the client directly.
Sign up, fill in your specialist profile and add your services — each with a category, a description and a price. Once the profile is complete, it appears in search and on the category pages.
Two ways: clients send you requests from your profile, which you can accept or decline; and you see public orders in your categories in your account and can respond to them.
You describe how you will do the task and give a price and, optionally, a timeline. The client compares responses and accepts one.
Contacts set to “Public” are visible to everyone on your profile. A client sees contacts set to “After connection” once you accept their request or they accept your response. “Hidden” ones are not revealed in new connections: a contact already revealed to a client stays visible to them.
Each service has a fixed price, a range, an hourly rate or “on request”. Prices show on your profile and in search results, and you agree the final price with the client.
Through search and the category pages of your services. The order depends on your clients' reviews — how many of them recommend you — and in search also on how well your services match the query.
A photo, a description, your region and way of working — online or in person — your contacts and a portfolio: photos of your work, each with a short caption if you like.
A client leaves a review after completed work, and only for a collaboration through Nexperity: they say whether they recommend you and may add a few words. Each client counts once, however many times you work together.
