SYSTEM I've been running an off-grid system with 24 x 450W panels connected in 3 strings to an EG4 18KPV inverter & storing in a rack of 4 x EG4 48V 100AH LifePower4 batteries in the home we are building in Puerto Rico since January 2024. We only got internet at the site last week, so I was...

I am not sure how to get the charge settings off the remote EG4 monitor software. Whatever the default charge settings on the EG4 batteries were, that's what's running. Thanks

Basic question about minimum sunlight intensity at which various type/brand panels produce power from sunlight. I assume that even for the monocrystalline panelsl for each brand that number is different. Is there a way to look up that number? - I do not see it listed in specs commonly. Is there...

"My specific case is a hybrid system, but the question also applies to the tie-ins:" The inverter would be a hybrid inverter, as stated.

i am not sure if this is the one you want to see or the PV from each string; they all look similar to this: the string above is 10 panels with 49.5V each, so 495V is the theoretical limit. i've been seeing 450V at the peak sun times consistently.

Thanks Quattro Have you ever taken a solar intensity meter to quantify the production? For example, Sunshine_Eggo puts up this graph here for his panels: https://diysolarforum.com/threads/replacing-mppt-for-6s2p-1kw-system-looking-at-victron-vs-epever.69855/post-884919 Meanwhile, the panels I...

Again, my hopes are to have a charged up battery pack for the monthly blackout event & may be offset a bit of the bill. Which one of those hopes is not attainable? I have a friend in the southern burbs of the Twin Cities (abt 40 miles from us) with an 8KW rooftop system who averages just over...

sorry, no. i am going to post battery charge and discharge power graphs; current is just the ratio of those to the battery voltage above:

my hybrid inverter is a hybrid inverter https://signaturesolar.com/eg4-18kpv-hybrid-inverter-all-in-one-solar-inverter-eg4-18kpv-12lv/ it is not a true grid-tie because it - let's see if i get the jargon right here - "has ac coupling" which allows automatic shut off from the grid loaprovide...
