Not necessarily. If you simply wire the on/off switch of the inverter to the load ports of the SCC, it should work. That switch circuit is going to be nowhere near 5a. Does require you to lightly modify the inverter, but it's a pretty simple thing that needs doing.

There's the cliffnotes right there! Higher torque without galling. I dont think anyone really ever talks about dielectric grease as a thread lubricant but i use it on all my stainless-to-stainless fasteners basically only for that purpose. I dont have a problem with anyone NOT using it, but i...

I bought a basically identical set of 'newtipowers' for $2400 at the time, and theyve been hooked up to my house for about 8-10 months. No big issues noted.. I did have to buy a $60 'equalizer' to balance between the 4 batteries in the series string.

What is your concern? Why wouldn't a 30kw inverter handle a 7kw load?

Ok so i think you are talking about this: https://signaturesolar.com/chiko-usa-residential-steel-carport-black-solar-pergola-solar-gazebo/ Which is exactly what i am planning to DIY this summer. Now i know the price to beat.. $8600. If i come in under that i'll be good. Honestly, since i...

Thanks for the update! Sounds one would need either two server racks or one with an upgraded BMS to get full performance from most 48v carts. I have a 48v cart and ive measured the peak draw but i forgot it!! I do remember it pulling about 60amps when doing top speed on level ground.

Yes, exactly. The MPPT has its own buck/boost converter function to always spit out power onto the DC bus at correct voltage. Then there is a buck/boost converter which can either a: step voltage from AC input down to charge batteries, or b: step voltage up from batteries onto dc bus to feed...

Did you floor it yet? 😁

In an all in one the inverter is feeding from high voltage DC bus. It's impossible for the inverter to work off 48v without stepping it up first. But, in situations where the solar power can cover the entire load, no or almost no 48v power is being stepped up and fed to the inverter.

Need more details on these inverters. Are they 48v all in one inverter/charger combo units? What are the existing batteries?

I have 460ah of lifepo4 in my rv, in the ugliest hodgepodge of mixed age and quality (but all cheap!) batteries on ugly mismatched wiring, and it still works fine. With lifepo4 there is no issue adding more in parallel, even if they don't match in brand/capacity/age. The epoch 460ah sure...

Based on the the fact that you already don't drop below '90%' i'd say the main benefit of switching to lifepo4 is you could choose to drain the batteries much further with no concern over how it will affect their lifespan. But honestly given how little you are drawing down your batteries...

I would stick with 12v as long as you can get an inverter that will power your loads. With 400ah of lifepo4 you could support some huge loads as long as the batteries are near the inverter and the wiring between them is large enough. I have a 12v system with a 5kw MSW inverter and 460ah of...

This is how i generally feel about it, although my knowledge of the subject is sparse. Ground rod discussions also seem sort of silly in the context of my mobile home which has 10 or 12 huge steel auger screws tying the steel frame of the structure into the dirt. Not only are there a bunch of...

I havent noticed any problem running midea 8k or 12k U units from my Growatts. I would highly recommend these units. If they had a good heat mode id like them better than the 2 actual mini splits i have. 🤷‍♂️
