Before I start fiddling I thought I'd ask questions and figure things out first, unlike last time. I bought the Sungoldpower TP6048 and man is it heavy! I wanted to ask advice on what settings for the battery would be best. I currently have a lifepo4 48V 50AH battery, just one for now and then more later. What should the battery type be, LIC? I also plan to set the output source priority to Sbu, solar supply priority to Lbu, charger source priority to Cso and beyond that I have no idea unless someone has recommendations for me?

Currently, I understand I don't have enough batteries or panels to run the entire load in the garage, but I plan to add more in the next few weeks of both but I'm hoping these settings will default on to utility when there isn't enough solar or battery to cover the load.
 
50Ah is woefully inadequate. IIRC, the minimum recommended is 200Ah.

Not only is it inadequate for "the entire load in the garage," the inverter is going to consume that entire battery just by being on without powering any loads, i.e., you have just enough battery storage to turn the inverter on, but not use any loads.

Read your manual from beginning to end.

Okay, I need to get more batteries. Should I not use the inverter until then? Is there any benefit I can get out of it now even if it is minute? Will this create a problem for the inverter or will it default to utility most of the time?

If you only turn it on when needed and turn it off when not in use, sure, it's worth using. If you have sufficient PV attached, you might even be able to use it without significant disruption or battery consumption during peak solar hours - say noon ± 2-3 hours.
 
So, really suboptimal but it's what I get for doing it piecemeal and maybe if I do it just right I can get something out of it. It'll be running servers that are on 24/7. Sigh, theoretically.

Not on paper but I know how much energy the servers, 2 PC, mini split, and lights use roughly. The servers alone are 400w.

I would refine the estimates as much as possible - get a kill-a-watt or similar. To just run the inverter and the 400W load, you're going to need 5X of those batteries and at least 2500W solar in good conditions (more for winter).

I've got 1600w in solar now and I've got my eye on 14*300w panels, I just need to do the math on the voc and amps to make sure it all fits. That should give me enough solar, right?

Know where I can get cheap or used batteries?

With the 6k inverter I never thought it would be enough to cover everything but at least put a dent in the electric bill, if that makes sense. But I'll make a formal power audit. The mini split is the hardest for me to nail down since it varies so much.
 
That's another 4200W. Another concern is the charge rate of the batteries. Many only permit 0.5C (25A = 1380W) or 1.0C (50A = 2760W), so you'll need to balance our PV output with your battery capacity. If the battery is full, it doesn't matter since it won't take any current once full, but you could easily trigger over-current protection simply by charging with too much current on so small a battery.

If I max out my panels and only have one battery, won't the charge inverter stop charging and switch to loads only since the priority is loads first? It might it still try to over charge?
 
I don't have the manual handy, but if the battery needs to be charged, and there is surplus solar, i.e., you're not using every available watt from the array for loads, it will charge the battery with that surplus. That could easily be over 50A.

Know your battery limits.
Know how your inverter may exceed those limits and take necessary steps.
 
The tp6048 works great without a battery at all.

50ah won't last long enough to do much. It might be useful as a ups solution which is what I plan on using my 48 volt mowers batteries for with my tp6048 but I'm running for now with no battery at all. The main reason I want the batteries from the mower attached right now is the unit gets stuck sometimes during power outages that are the fast on and off type of power losses and requires me to turn the ac feed breaker off and back on to reset it.

It of course depends on how much power your pulling from the battery too. My tests so far do fine powering it from the mowers 100ah setup with 1300 watts of load on the tp6048.

Since its a hybrid setup its happy to get what it needs from the power company for its needs.

So basically to start using the thing all you need is power going in from the power company and going out to a load box. Whatevers in the load box will run from the power company going thru the unit.

To make use of it you need 120 volts dc from the panels for it to go live so to speak and start shaving off power required from the grid. That's how I'm using mine now.

I will be building a real battery for mine soon but the mower will serve as a backup battery to keep it from getting locked up from power blinks if its dark outside. I found that just a few hundred watts of pv keeps it from locking up during power blinks even though that isn't enough solar to cover the loads.

Enjoy the unit I sure like mine so far !

Sorry for the late reply just got back from vacay. Good points, I'll be sure to research and know those answers from the inverter side of things.

Thanks for the input that's how I plan to start using mine. I have a bit more research on some used PV panels and if they fit I'll purchase and additional 14, hopefully and start shaving until I get more batteries.
 
Hello! I’m hoping someone with experience with the Sungold power TP6048 could post what settings they are using when connecting the Eco worthy battery bank (asked in the initial posters question, but not answered yet in this thread). I will be connecting 4 of the 48 V 50 amp hour batteries in parallel for a 48 V 200 amp hour lithium iron phosphate battery bank. I really want to get the settings dialed in for maximum lifetime. Thanks a lot for your feedback!
