Sufinanciranje je moguće neovisno o tome je li priključna snaga mala.

Here je li introduces an indirect yes/no question, so in English it is usually best translated as whether or sometimes if.

So:

• neovisno o tome je li priključna snaga mala = regardless of whether the connection capacity is small

This is different from a direct question like:

• Je li priključna snaga mala? = Is the connection capacity small?

In your sentence, it is embedded inside a larger structure, so je li means whether.

In standard Croatian, je li is generally preferred, especially in formal and written language.

So:

• je li = more standard, especially in formal Croatian
• da li = also understood and common in speech, but often considered less formal or less elegant in careful writing

Because this sentence sounds administrative/formal, je li is exactly what you would expect.

Literally, it means something like:

• neovisno = independently
• o tome = of/about that

So the whole phrase is roughly independently of that or more naturally in English:

• regardless of that
• regardless of whether...
• independently of whether...

This is a common formal expression in Croatian. A very close alternative is:

• bez obzira na to = regardless of that / regardless of whether

So your sentence could also be phrased as:

• Sufinanciranje je moguće bez obzira na to je li priključna snaga mala.

Tome is the locative singular form of to.

The preposition o normally takes the locative when it means about / concerning / with regard to.

So:

• to = that
• o tome = about that / with regard to that

In the phrase neovisno o tome, the structure is fixed:

• neovisno o + locative

That is why you get tome, not to.

Sufinanciranje means co-financing or joint financing.

It is a neuter noun formed from:

• su- = co-, together
• financiranje = financing

So sufinanciranje is the act or possibility of costs being covered partly by another party, often the state, a municipality, a fund, or some institution.

This is a very common word in official, legal, and administrative Croatian.

Je moguće is a very common Croatian way to say is possible.

So:

• Sufinanciranje je moguće = Co-financing is possible

You could sometimes also express possibility with moći, but that would change the structure:

• Može se sufinancirati = It can be co-financed

That is a different sentence pattern. Your original version is more nominal and formal, which fits official language very well.

Because it agrees with priključna snaga, and snaga is a feminine noun.

Croatian adjectives must agree with the noun in:

• gender
• number
• case

So:

• snaga = feminine singular
• therefore mala = feminine singular

You can see the agreement in:

• priključna snaga = connection capacity/power
• priključna snaga je mala = the connection capacity is small

This is a noun phrase made of:

• priključna = adjectival form meaning connection-related / connected / grid-connection
• snaga = power, capacity

So priključna snaga is literally something like connected power or connection power, but in technical English it often means connected load, connection capacity, or grid connection power, depending on context.

Grammatically:

• priključna is an adjective
• snaga is the noun it modifies

Both are feminine singular nominative here.

This is a standard Croatian structure:

• neovisno o tome
  • clause
• bez obzira na to
  • clause

The phrase o tome or na to acts as a kind of bridge to the following clause introduced by je li.

So the logic is:

• regardless of that—whether X is true

This sounds very natural in formal Croatian. English often compresses this more directly into regardless of whether..., but Croatian commonly uses the extra element o tome or na to.

Yes, Croatian word order is fairly flexible, but not every version sounds equally natural.

The original:

• Sufinanciranje je moguće neovisno o tome je li priključna snaga mala.

is perfectly natural and formal.

Possible alternatives include:

• Neovisno o tome je li priključna snaga mala, sufinanciranje je moguće.
• Sufinanciranje je moguće bez obzira na to je li priključna snaga mala.

These all mean essentially the same thing, but the original sounds like standard administrative style.

Yes, very much so.

Several features make it formal/administrative:

• sufinanciranje is official vocabulary
• moguće is a formal way to state possibility
• neovisno o tome je li... is a formal linking structure
• priključna snaga sounds technical

In everyday speech, a speaker might choose something simpler, but in regulations, notices, application rules, or technical documentation, this sentence sounds completely normal.

Not with the same meaning.

• je li here means whether
• ako means if in the sense of a condition

Compare:

• neovisno o tome je li priključna snaga mala = regardless of whether the connection capacity is small

But:

• ako je priključna snaga mala = if the connection capacity is small

That second version introduces a condition, which is a different idea. Your sentence is not conditional; it says the result holds regardless of that factor.

Yes. Moguće is the neuter singular form of the adjective moguć (possible).

It agrees with sufinanciranje, which is a neuter singular noun:

• sufinanciranje = neuter singular
• moguće = neuter singular

So:

• Sufinanciranje je moguće = Co-financing is possible

This is a straightforward subject + to be + adjective structure.

Yes, mainly these three things:

1. Croatian uses a more layered structure

   • neovisno o tome je li...
   • English often just says regardless of whether...

2. The embedded question uses je li

   • English learners may expect a simpler if
   • but Croatian marks it as an indirect yes/no question

3. Agreement matters

   • moguće agrees with sufinanciranje
   • mala agrees with priključna snaga

So even though the sentence may look long, it is built from very regular Croatian patterns.
