Hello All,
I am a complete newbie to solar and all the numbers. Sorry for any silly questions.
I have a solar grid that has 12 panels x 550W = 6600W or 6.6kW (that's one number I figured out).
My question is, I want to pair this with a battery and inverter. What would be the most optimal options?
My current usage is not much, but this will be used for a small house that is being built. It's completely off-grid. More panels may be added later if the need arises. For now, I want the most optimal and maximum possible battery and inverter options.
I have the below options from a seller:
5.5 kW inverter + 51.2v, 200Ah Lithium Battery pack = 10.2 kW Battery and 5.5 kW inverter. Is it okay to use a lower inverter and more battery storage? Or should it be a higher inverter and lower battery? Or should I use a 10kW inverter and 10 kW battery pack? Since this is higher than my solar panels, what would be the downside? Slow charging? Would this be future-proof if I add panels later?
Another option is 5kW and 51.2v, 100Ah = approximately 5 kW battery and 5 kW inverter.
Or are there any other options recommended?
Another question is, what if my battery usage is minimal for now as the house is not done yet and the only connected things, for now, will be a pump for irrigation (2.2kW will be used with solar directly, and if no sun will use battery, watering will be for a total of 30 - 40 minutes max a day), CCTV cameras, wifi routers, and long-range wifi extenders, since this is Lithium batteries and there is no discharging as there is no usage, it would be ok right? The inverter will be protecting the battery correct? Will it in any way affect the life of the battery?
Thank you.
