I spoke with an ABB rep. The DC bus can be fed directly bypassing the input diode pack altogether, I'll report back in a couple months when I receive, this and look at it, as I think this maybe useful for some off grid people here. Referring to Hedges excellent points, I think an additional...

Please excuse waking a sleeping thread. I'm looking for a high voltage mppt charger to fill a custom Lion battery pack to user specified voltages. Goal 320vdc and or 170vdc. Any experiences with custom Lion?

Thank you. I'm busy researching and waiting on answers from manufacturers. If I can find suitable chargers/inverter/vds and other means I will add knowledge. I suspect there is a coming change in battery voltage, Solis and Solax, and SunnyBoy are using higher voltage stuffs. Solar Panel...

Please excuse waking this Rumpelstiltskin forum, this is a an exceptionally applicable read for my plan. As much as possible a DC house farm. Any new info?? I previously found the Solis, and have heard a little reliability issues, I have found no other high voltage battery besides the sunny...

Thanks, Good cautionary, will consider diodes and transistor on bus feed, which is allowed. Water pump rarely could ever back feed power during braking, set them to coast. Wondered also about feeding DC through AC diodes without rest. Somehow, your mention, caused me to think that a simple...

What are everyone's thoughts on what might be likely ideal or standard voltages might be? 240VAC has a peak voltage of ~340 (non rms value). My "solar" well pump is a standard 3 phase motor, running off of a Solar ABB VFD, which receives power in the same terminals as single phase VAC. Other...

JohnGalt1717, read your note, but I don't know what it is or your referring to. Efuse what is a hot swap controller? It sounds interesting..
