I voted this up BUT feel like I can add some supporting information and ask the question why can’t we have both? Meaning a GUI toggle setting that allows am amp centric way of viewing things or watts centric view. I’m life long sailor and I too have always thought in terms of Amp Hours but more recently have been trying to convert a Watt Hours way of thinking. My house has 41 solar panels roughly 10KW, I generate between 40-60Whrs/day depending on the time of year, my house consumes 1MWhrs/month plus/minus depending on time of the year. My utility bills monthly in KWhrs. For my house Watt Hours make sense.
My sailboat had 3X80Watt solar panels and I had 1200Ahr AGM bank, always thought in terms of 100Ahr/day was consumption and what could my panels give me in terms of Ahrs/day. My “thinking” conversion to Watt/hrs happened on my current trawler this year when I replaced 1350Ahrs of AGM batteries with 1200Ahrs/30KWhrs of Victron LiPoe4 batteries and replaced my inv/chgs with Victron MPIIs. My Sailboat was 12Vdc setup, my trawler is 24Vdc both had/have now 1200Ahrs of capacity but twice the voltage means twice the energy density. P = I x V So my Sailboat had a roughly 15KWhrs of capacity while my trawler now has 30KWhrs of capacity. This summer I added 1000W’s of solar to the roof of the trawler and I started thinking in terms of Whrs of solar generating capacity going into my 30KWhr bank. I still like to see amps it makes me feel good, it seems commonsensical to me BUT I’m starting to get the Watts concepts too!
My laptop has 100Whr battery, I see electric vehicle specs all have battery capacities of 50-100KWhr battery packs. The cars are talking in terms of watts/mile not amps/mile, so I want to change my “thinking” but man I still love me some amps. When those solar panels get full sun at noon and I see 25Amps at 28V’s going into the battery I think that’s good BUT in reality why am I only putting in 700Ws when I have 1KW of solar panels on my roof. I know there is conversion efficiencies and loss but my point is if you only think in terms of Amps you miss out on some of the energy information that Watts or Whrs gives you. So IMO Victron should support viewing both ways as it’s just a math calculation and a GUI setting to toggle……
