new to the field, setting up an off-grid sys, possibility for upgrade
So I'm setting up a 3000W 24V system for budget reasons, and would like to upgrade it later on to 5000W. Would it be possible to get instead a bigger inverter/charger for 5KW (5000W 48V charger inverter with 80A MPPT regulator - NOT the one in the set: Inverter + Charger + Controller MPPT 3000W 24V) to fit with panels (6x Solar panel 275W of 60 cells Bauer) and batteries (4x Ultracell UZS 600Ah 6V Stationary Battery) for 3KW, and on a later date get more panels & Batteries? Being so new to the topic and with little technical experience, what else am I not thinking off..?
PS, I'm in Portugal, the set is from Spain (as local prices are ridiculous) and probably have different brands to offer.
