hello
Firstly thanks in advance for any advice that people may be able to offer.
I have a basic plan for a solar setup
REQUIREMENTS
1) run 6LED 12v lights
2) a small 12V compressor fridge (WEBASTO Cruise 130 Elegance - consumes about 418W/24h)
3) washing machine (day use only planned on 1hr short cycle) - https://www.johnlewis.com/bosch-ser...-machine-7kg-load-1400rpm-spin-white/p4917463
4) fiamma water pump (estimate 1hr/day total) - https://www.fiammastore.com/Fiamma-Aqua-Pumps-for-caravans-and-motorhomes/Fiamma-Aqua-8-pumps
5) use 2hr a day a 12v-->230V 3000W inverter to run a 2000W induction stove - https://www.campinggrej.dk/shop/carbest-sine-wave-85350p.html?CookieConsentChanged=1
7) charging mobiles
PLANNED SYSTEM
Location = Northern Spain = 3-4 daily sun hrs
2 x 450W JA SOLAR (144 cells, mono), 24V https://www.bricomart.es/pub/media/..._solar_mono_perc_hc_10940412_techsheetsup.pdf
---
2 x Victron 12/24V, MPPT 75/15 - https://www.victronenergy.com/uploa...MPPT-75-10,-75-15,-100-15,-100-20_48V-EN-.pdf
OR
1x 3600W inverter/charge controller
https://assets.leroymerlin.es/is/co...s/inv-car-ais-m-power-um-v4-3-6k-24v-120a.pdf (this system leaves space to grow as our power needs will increase over time - as we build more. BUT its way more $$ upfront. Eventually would love to charge a small electric car one day, not sure if this unit will do it tho)
---
2 x 260AH sealed 12V AGM ELEKSOL batteries (in spanish - https://www.bricomart.es/pub/media/...para_sellado_v_ah_c_10195822_techsheetsup.pdf)
CONFIG
Basically plan to hook each panel to a seperate MPPT then both to the 2 batteries that will be wired in parallel
OR
just hook panels and batteries direct into the inverter/charge controller unit (batteries as 24V in series)
QUESTIONS:
a) Am I on track or totally off on my panel sizing in relation to planned usage?
b) How about the battery sizing? As I will only use the washing machine during sunny hours I assume I may not need extra capacity for the battery? Is that correct? any comments welcome
c) for the victron MPPT option spec sheet says 'Nominal PV power' is 440W but the panels are 450W. Is this a problem? I ask cos I dont really understand what Nominal PV power is and how serious the number is. Having trouble finding 400W panels that are 24V in my area.
d) JA solar - looking online and not really finding many reviews on it. Youtube has a couple but mainly from stockists as I see. I am wondering if anyone has experience with them. In peoples experience do brands of panels make much difference?
e) any obvious cheaper ways to achieve the same setup?
Thank you
