Pump seems reasonable build quality and brushless variable speed should be less wear, but I guess you still need to replace the seal once a year, source for it?
The 900watt is for 1.5" pipes, the 1200watt pump is for 2" pipes, so you maybe have make cuts and adapters on your pvc pipes.
The 10meter (32.8feet) red/black panel cables are 14AWG and no y-adapters are included but you need to run series-panels in Parallel to get the 90-120volt at around 1500watt., I ended up finding used 180watt panels at 17/cent a watt, so I do 4x2.
Leehitech 1 Pair Solar Panel Connector Y Branch, is only $4.56 and jamgoer 30FT 12AWG is $26 (not necessary but recommended), Use the extra mc4 connectors you get with these two additions and then use the included vevor 14awg to make patch cables going to the y main trunk.
