i dont have any special love for a specific brand.. its just they are better than any other option available here.. had there been a better brand i would have preferred that.. unfortunately we are stuck with limited choice and limited stock availability.. and local brands are over priced for their features and capacity.
MGE inverters used to come but they dont any more, so did a rare few pieces of Schneider industrial.. no more.
as for the steps, you are again reversing them..

I dont really need the inversion step 12VDC-220VAC to so I can convert it back to 12V using the stock AC-DC adapter
its 220V UPS ---> direct adopter DC V... one step solar power is coming from another source and simply adding upto batteries.. not being converted.
your original way in 1st post was Wapda 220 -> Adopter 15V> CC 12V > Battery> Router. dont you see any problem in this?
now you propose offgrid Panel > CC > battery > router.
even in this situation, consider having 2-3 rainy/ cloudy days, when all your battery power is consumed and you have no way to charge it except using wapda again which you didnot connect cz trying to make its independent.. offgrid completely isnt possible then in such situation.
why go total offgrid when you can do hybrid? add panels to same battery set in future along with UPS and it will keep it topped up for free and wont consume wapda at all in day for charging battery, as they will be in float from solar and more backup from unused power in night .
you WILL 100000% increase your load demand in future.. everyone does, power is most important necessity. will your entire setup be able to provide any AC power? no, cz it would be just a DC 12v setup, you would have to add an inverter to utilize your excess power for anything 220V else. the cost of adding an inverter will again add up to your current scenario.. or would you rather buy a new set of CC, panel, and battery for Every single item you need to add in future every time you need free solar?.
you are going to spend quite a few bucks for your current setup. why not go for a one time more for future proofing it.. you can do with ANY UPS..even a good desi ups will work will future solar upgrade as yousaf is already using at his home fine. cheaper ups will save you a lot.
PS: i am not in mood to fight / Behas for the sake of Behas for proving self righteousness with anyone else.. it was just a practical suggestion for OP from my perspective only... if OP is up for electrical experimentation, he is most welcome to try .. this post is NOT UP FOR DEBATE ..
