I wanted to start this thread so folks have a place to compare real-world numbers about their generator efficiency. This data is from two generators which I run exclusively on propane. Up to 2022-11-10: Champion 100263 (Nominally a 3400 watt generator) After 2022-11-10: DuroMAX XP9000iH...

Some things I've learned about the DuroMAX XP9000iH - hopefully some of this will help other folks: Similar Generators This generator is very similar to the following generators which can be used (with a grain of salt) as a reference when looking for helpful reviews, alternate manual...

I'm guessing that many other folks - like me - have also accidentally shorted in reverse their power supplies while top balancing such that somewhere between -12v and -56v flowed through the power supply. When this happened to me, sparks flew and subsequently the power supply stopped working...

Hi Folks! I've been playing with various off-grid systems for a while now, but just starting to get into building my first LiFePO4 system. With any building/design project, one thing that really helps me think through the spatial and material requirements is being able to visually assemble the...

We'll call the time where a system is neither all the way full nor too close to empty: "coasting" IMHO, time spent coasting is one measure of how well an off-grid system is balanced in terms of production capacity, storage capacity, and usage. Lots of ways to look at this, but; If your...

Hi, I just wanted to share my post MultiPlus Inverter Metrics since I hope it will be useful to other folks trying to monitor their split phase / parallel / 3 phase Multiplus installations via VE.Bus/MK2/3. Please feel free to use this thread to provide feedback or discuss and ask questions...

I'm curious whether anyone has worked out a circuit that bypasses one of the panels in a PV string at low temperatures? It seems like such a device could be very simple and allow normal operation with larger strings than the temperature coefficient and absolute lowest expected temperature might...

I have two (in parallel) DIY 8S LF280K batteries with Overkill BMS' that I built this fall. (Charged cells as a pack with BMS, then top-balanced individual cells to 3.645v and <0.5a.) Recently, I've been observing some interesting behavior with the cell voltages that I'm hoping someone here can...

This is a great forum where folks seem eager to help each other and share their learnings, experiences, etc. It is awesome to see such a mix of knowledgeable folks and beginners trying to learn... However, we see the same questions (or minor variations thereof) super frequently. Often the...

Not a "complaint" exactly, but this section is the closest to a "Meta" forum section I could find... WRT: https://diysolarforum.com/threads/official-forum-code-of-conduct-and-terms-of-service.2216/ I'd like help understanding the following clause better; I read this as a injunction against...
