Thank you for the reply , sounds like big effort to get it setup , here I was thinking you buy a ready made kit for your needs and it is plug and play
there are probably small "kits" that will include everything, but it isn't that simple.
absolute cheapest simplest way would be:
small inverter (pref sinewave but you could possibly get away without it or add in an inline ups) - your load will be small, that is probably less than 300W i guess at peak, you should decide if you want to cater for slightly bigger. so imo minimum 600W inverter.
then battery, ultimately you want to go for Lithium/super capacitor etc but for your application it is mental, here a gel or deep cycle battery will do you just fine, its lifecycle will not be great though. if the inverter is 12V you could get away with 1. 12V x 100AH = 1200W - divide that by 2 for a 50% depth of charge and you are sitting at 600W which gives you about 2hrs run time at your 300W load (note these are just rough numbers)
then you need a solar charge controller and a panel(s) to charge that battery and run loads. if you have a bigger array than your need for battery charging it means you can run while you charge, thus you can also then effectively run without the battery restriction while there is sun. To work this out take an estimate that you need to charge your battery in 5hrs of sunlight, to replace 600W in 5hrs you need at least 150W an hour (i have bumped it a bit to cater for some losses). so if you want to run at the same time you need at least 150W + 300W = 450W worth of panels.
imo 2 x 250 worth of panels would do nicely and you would very likely have some room to charge a phone etc. for that you would need at least a 20A pwm charge controller. (it would be preferable to go mppt but we are trying to keep costs down here and not exactly aiming for the ideal)
so
~600W inverter
1 x 12V 100Ah "deep cycle" battery
1 x 20Amp pwm charge controller
2 x 250W panels
Cabling, fusing + mounting brackets
The options are so diverse it is mind boggling.
if you want a kit form this would work well. though imo they are under speccing the solar capacity. nice inverter and charge controller though. you could get more or better building it up though.
