Assuming that grid code specifics could be worked out, what would be the point of failure where a power company would disapprove of a Victron based system with MPPTs, a Multiplus, and a VM-3P75CT meter etc? Is there an actual Victron hardware deficiency or incompatability? Is it a regulatory...

Thanks ricardocello for stating this out right and clearly. This is a conclusion that I have been arriving at indirectly on my own. I have a small 1.2kw split phase system with a pair of 48/3000/35 Multiplus 2 inverters running systems in my greenhouse. I want to expand to services in the house...

Roger that. W/my new Chin I'll be at 51.2v 100A versus a series wired bank of (4) 12v 200A which would've put me at 48v 200A.

Appreciate your sharing your logic w/us. While I was attracted to the additional amperage provided by (4) 12v 200A in series, the simplicity of not having to deal with a controller (one more box) won out.

Appreciate your detailed response. I pulled the trigger last night after Crowz post and picked up a 48v (51.2v?) 100A Chin battery on Amazon. According to Will Prowse, Chin batteries may be manufactured by AmpereTime as well, and appear to have at least good build quality. Best regards.

What brand did you go with?

That's not the one. That is just an example of a mfg selling 4 batteries for series wiring.

I am hearing the siren's call of cheap 12v 200A battery packs that can be had during Black Friday sales. I am interested in using four of these wired in series to create a 48v battery string. Once the packs have all been balanced by bringing to a similar charge state, how often does this...

Two 200w units currently reduce ice buildup. Looking to do the same w/12v heaters of similar capacity. Question is whether using a controller in this manner (without batteries) would result in damage to that controller.

The 12v units that I am looking at are extremely basic. https://www.amazon.com/Dernord-Immersion-Submersible-Element-Stainless/dp/B0761L2Q8M/ref=asc_df_B0761L2Q8M/

So, would there be damage to the controller (or the panels) if the batteries were disconnected in the winter and 12v went directly from the controller to the 12v heating elements in the greenhouse water tank, (" the water battery") ? Then in the late spring, when the fans are needed, simply...

Currently have (2) 200w heaters in place in Dec/Jan that reduce ice formation in the water tank. Need at least this much input. Any thing above this would go into general heat gain. Would likely just let the heaters run full time. Basically the water tanks would be my "batteries". Have good...

Hello- I am thinking of adding (6) 200w Rich 9BB panels to the front of my attached 600sqft greenhouse. Greenhouse has 2,000 gals of water in it as thermal storage. I was planning to use the panels to add a bit of heat to this water in the fall, winter, and spring, and in the summer use the...
