Just to repeat and add to the above;
Your requirements could be filled within a 1500 watt setup.
Go for a minimum of two batteries having 200 AH each. Liquid or dry, doesn't matter. Liquid batteries were being used for the last thirty years and they still are because of their low cost of replacement.
Infinisolar inverter is much better than the mks Axpert. Both are made by the same company. Infini is expensive but it can handle more watts than mks. Useful if you feel like adding more panels down the road. And in case of a power surge infini will fare better than mks.
KVa is not the same as kW. Beware of sellers who talk in volts instead of watts. Acquaint yourself with your appliances watt requirements before going into the market. Go to multiple vendors. Educate yourself. They're looking to make a quick buck. Be careful.
Overseas, companies are giving twenty five years warranty for their solar panels and ten year warranty for the inverter. Plus after sales services.
MPPT solar charge should be built into the inverter. Nearly all panels are built in China but to sell them in the market they're also made in Philippines, Spain, France, USA, Germany etc. A panel costing less than Rs. 85-90 per watt is definitely Chinese. Solar panels are also sold on Ali express! There are three categories of Solar panels, A, B and C. They differentiate from one another in only one category ie, amount of sunlight converted into usable current. Some vendors are selling C category panels with A category stickers stuck on them.
There is a company in Lahore by the name of peakworx which is selling quality solar solutions.
Then there is Nizam group of industries. They are based in Lahore but have an office in Rawalpindi. They started with residential and commercial solar solutions and are now busy building solar parks generating mega watts of electricity. Check with them also.
