I think that is the $69 version "monitor only" https://www.amazon.com/Emporia-Energy-Monitor-Electricity-Conserve/dp/B07R11H2Q2

Yes, I just saw them on another thread yesterday. I'm thinking about ordering one. I'm hoping that I could install them around the main 120v cables on the front of the house.

That makes a lot of sense. Similarly most of my 230v loads are non-essential like the pool pump and the washing machine. The electricity cost here in Barbados is about USD $0.33 per kWh, so anything I can save is certainly welcome! We have plenty of sunshine, so solar is kind of a no-brainer...

Thanks for that, a helpful rule of thumb. Yes, it would depend on the panels. I've seen some 370W panels with a VOC of 40v, which would work well in a string of 6 and be under the 250V input of many of the combined units (e.g Growatt or a MPP LV6548 if I went for them). OK, that is a larger...

Yes, you are right it might be a bit over. Temperature here is a pretty stable 24-30 degrees C. When looking at the total voltage, is it the Voc you need to look at, or the voltage under load?

I guess one usecase that might go against this, is if you are wanting purely a battery backup system. ie. you want to use grid power/solar for the majority of the time, and just want a battery for backup in case of a grid outage. So maybe you want the battery to just give you an hour of power...

Or a pair of LV6548's... decisions decisions. If I went for 24 x 400w panels, then I'd be able to run 4 strings of 6 panels, each string at 250v to each of the four solar inputs across the two units.

OK... having just written all that, I may have already changed my mind Having just seen iSwannie's posts: https://diysolarforum.com/threads/residential-off-grid-48v-growatt-solar-hybrid-30-day-overview.37391 Just seen the Growatt system and BigBattery products...

Hi, I'm going to be setting up something that sounds kinda similar. What is your battery bank size? Is that 600Ah @ 48v, eg 28kWH? Our house uses approx 35kWH a day, and I'm hoping to similarly have the solar carry the load during the day and the batteries mainly used at night. So trying to work...

Hi All! I'm about to (hopefully) embark on my first residential solar project. I've got an engineering background, and previous converted a deliver van into a fulltime camper and installed solar in two campervans. So I've got some experience in solar, but on a much smaller scale. I'm also into...
