You will have problems with surge demand from The pump when it starts up the amp draw is higher than rated amps and with a small 2000 watt system it is probably going to trip it.
I run 2.2 v 48 volt 8800 watt system the battery amp hours are 1400 and in 30 min the well pump can drain the system dry. I use a 3/4 horse pump motor. Without pump and pressure tank I can keep 2 big freezer chest size 2 million lumen of led lighting, fans a full sized fridge and household electronics minus a TV and ham set running, washer dryer industrial sized for 3-5 days no problem .
quality parts.on solar is a must it’s a 25 plus year product if it breaks at the 5 to 10 years you won’t have even made return on investment.
Cheap solar in a pinch better than nothing but you are buying nightmares later. Cold battery room is recipe for disaster just like too hot. Buying golf cart batteries is cheap till you have to buy 5 to 7 sets to one good set of surette rolls.
Cheap panels cheat you two ways first they are allowed a 10 percent production loss so 220 is 200 and can still.be sold at 220 price. The decay rate and soldering faI lure from micro stress fracture over 10 year is 20 watts per year so a 220 panel cheap in 10 years will produce near 0 and be in design specs.
The best real world tested panels are day4 they are not cheap they weigh a ton. They send you balanced system panels granted to be over stated wattage. No I don’t work for them but have been involved i a few solar farms on industrial grade. Their one farm in Germany has 15 years of run Data it has lost total of 2.2 percent capacit but started 5 percent over state wattage.
Just be wary lots of cheaters and liars in the solar game read the small print. You can buy decent panels for just over $1.25 a watt when buying a pallet, go with 315 watt panels they are now standard for.industrial installs and are more stringently montored, lower watt ones are mainly the failure to pass inspection.
I hate to say it but a descent long lasting solar off grid for a Modern house will set you back 35k for quality you can save if you can assemble and can build racking and do wiring.
