My domain is: [gate.ru](http://gate.ru)

Hello  
We want to create a lot of domains like {domain}.wp.gate.ru  
I’ve read that Let’s Encrypt limit is Certificates per Registered Domain (50 per week).

What is a registered domain in our case? Is it means that we can use let’s encrypt only for 50 domain like {domain}.wp.gate.com per week?

The Registered Domain in your case is `gate.com` / `gate.ru`. And yes, it means you can only get 50 certificates per week for _new_ subdomains (excluding renewals).

If you are creating some sort of hosting platform using your `*.wp.gate.ru` domain, then you may apply for a rate limit exemption based on that domain and/or your ACME account.

You can find the link to apply for an exemption on this page: [https://letsencrypt.org/docs/rate-limits/#a-id-overrides-a-overrides](https://letsencrypt.org/docs/rate-limits/#a-id-overrides-a-overrides) . It usually takes a few weeks to get a response.

You can also just try using a single wildcard certificate for `*.wp.gate.ru`, and using that to protect all of your domains.
