I seriously don't understand. We have a small forklift and need to charge an AGM 36V pack. Having massive current is not even that important, but I want it voltage regulated or even just adjustable. I can find them no where! However, as soon as we step into the solar arena, now every charge...

I am running a new load monitor that has internal resistance displayed. However, I am not certain how to interpret the data as it changes with load, and reads all zeros with the parasitic 20W load against a 600ah/12V pack.

For Tim, who asked for a link. About 4min in. Basically this thing works to create perfect output, BUT probably at an efficiency loss, which I don't care about. Lots of people get spun about perfect power but don't realize most electronics take it right back to DC anyway! Basically all I...

There is a test video on YT that proves the MPP LV-MK does it as well. Just not certain how each does it, and that is something I always get crickets on. OEMs don't talk about designs. I am just supposed to throw big dollars at a mystery box. Schneider is the worst!

I am confused as you say Victron is the only one with "grid assist", or maybe just the terminology? Or maybe the architecture is different? Maybe it truly does sync the sine waves as AC? Which would certainly be more efficient! I really tend to wonder if the Voltronics goods are just...

That is quite interesting! From what I gathered, a lot of this comes down to software. I've read several places where the PowMr looks the same but does not work well at all and I have one of their brand new 60A MPPT chargers that is basically a paper weight! The electrics inside might be OK...

This won't be grid connected. In most inverters, they use a transfer switch so when AC is present, they activate a transfer switch, which completely removes solar and battery from powering the load at all. I'm sure the internal solar charger will still charge batteries, but my goal is to allow...

Well, there really has not been good, standardized terminology. Someone starts it, and others sort of follow. Like "SUB", I understand that is a priority setting, but means nothing in terms of ability. Only thing I can guess is a "double conversion" unit. I guess the nice part of that...

I very much realize Victron has their "power assist", but I have yet to find a common 'term' for the ability of an inverter to sync and use both generator and solar power, or grid for that matter. Maybe a "hybrid" does this? Being in the engineering field, I understand a lot of what they are...

Yeah, it is a certainty that digital soft starts will be used. No way around that. Actually, I may also supplement the bedroom area with a mini split heat pump so the big power hogs don't always have to be running and I can grab some heat as well. Actually just not having to listen to those...

Not sure if your compressor fridge is 12V. Many are, which basically run a lower power compressor system. I've tested other fridges at around 300W when running but have not tested this one just yet. I think a lot of people have fought with absorption fridges but mine has done well for me...

I think one direction I am looking at is keeping the small 12V battery bank and the OEM 12V battery charger that runs off the AC, then use the 48V bank only for AC power and keep that as a discrete system. This would hold the 12V voltage up where it should be and if I lose AC I still have 12V...

Probably targeting 3000W right now. What I am most interested in beyond the voltage is an inverter that is capable of running solar combined with the generator. Usually it is one or the other, which is just not acceptable for my application. Basically I want to run at least one of the air...

We use a 5th wheel as an office at a plant nursery but also like to use for a couple trips. I say this because we run it off of solar primarily, but not really enough power. There is no grid power. Right now a 5th is setup with only a 1000W 12V inverter and separate charge controller with a...

We will probably have to make do for the moment but I am curious about the latching DC solenoids? Been around irrigation for decades but can't say I've seen this. Our current AC solenoids are 200mA, 4.8W after inrush.
