ipanda makes a high voltage MPPT solar charge controller that Mike G used it was bought from alibaba or aliexpress... a chinese product...

ipanda makes a high voltage MPPT solar charge controller
I do not see high voltage but 24 volt and 60 amps . Who is Mike G ?
Mike G is the man who is doing the high voltage YouTube videos. in May and June of 2022....
Mike G >>>> he used the Ipanda high voltage MPPT and the Sandi high voltage 25k and also had a 20k inverters as a backup. i think he has about 6 or so different YouTube Videos....of his high voltage off-grid solar PV setup ....very interesting....
the ipanda high voltage mppt he used (Mike G)was good for 26000 watts of solar panels at high voltage....perhaps one would have to contact the company for a custom made one...🤔 I think he said it cost 1300 dollars including delivery for the high voltage mppt
at least that was what he (Mike G) was showing in his high voltage off grid PV system...
how many make sky blue chinese mppt are required for 26000 watts of pv panels? then each would also require a run of two wires also.. correct....??? buried so the lawn mower does not eat it....
Sean was always promoting the chinese make sky blue mppts for some reason but does not sell them....
I bought 120 solar panels in pallet quantity from santan solar and the freight was about 350 or 400 dollars for every 40 pv panels I ordered...likely more now with the skyrocketing diesel and gas prices...🤔
maybe
25 kw inverter and 20 kw inverter in aqua green floor model higher voltage inverter might be a good option also...
Zhejiang Sandi Electric Co.,Ltd, Posted june 14 about the Sandi 25kw inverter .
Mike G has a 230v DC system with 72s LifePo4 and 144 battery total . He use active balance and it works for him . He say he do not use BMS and his friend use BMS and overcharge the LifePo4 and the fire burn the building down and eveything inside is gone .
I watch more of his youtube and he is smart and brave to make a 230v DC off-grid system . I can not use my 4 ton heat pump off-grid but need do what he do with a portable AC to keep his Sandi cool at 70 degree F and then I can next year with a 12 kw inverter . NO off-grid inverter works in 120 degree heat .
I use 5 MSB for 5000 watt of San Tan panels and copper wires cost too much now .
Sean was always promoting the chinese make sky blue mppts for some reason but does not sell them.. He can not sell MSB cheaper than ebay and has no contract to allow him to sell . He has 2 MSB on the wall that he say is the best .
I bought 120 solar panels in pallet quantity from santan solar and the freight was about 350 or 400 dollars for every 40 pv panels I ordered.. SanTan will not make Sean an affliate on his last youtube . I live a few miles fron their warehouse and they sold out all the panels wihout Sean help .
He say he do not use BMS and his friend use BMS and overcharge the LifePo4 and the fire burn the building down and eveything inside is gone .
The problem is when people use the BMS like the perfect solution, "just throw one of those on there and do anything, you'll be fine."
A BMS (if used) should be treated as guardrails (at best). If you "guide" your car down the street with the guardrails....it won't last very long.
I personally don't have a BMS on my battery bank. Yes, I do have custom GS balancers on it (a must!), but all of the other protections are in the settings on the connected equipment. If a "BMS" were added at this point, it would do nothing--as it should.
Mike G off grid PV system:
one high voltage (240 volt) ipanda solar charge controller and one Sandi 25k high voltage LF SP PSW inverter with a high voltage battery bank and a pallet (or two) of solar panels would make an efficient system....
very interesting for sure....
i could see the pre-built battery from Sandi but the cost saving of DIY battery with LiFePO4 280Ah cells is still interesting....
Jack Rickard (of evtv motor werks) was doing the high voltage PV systems with the tesla car batteries....
the battery storage is the most expensive part of a large system today....(ESS) aka energy storage system >>>> abbreviations everywhere....
I think the lack of YouTube videos of high voltage equipment is due to an increase danger liability issue....kind of like Sean no longer says to open the powerjack inverters>>>>that used to be a standard and is the only way you find the loose wires or floating nuts or other things that occur during shipping.... ups and FedEx do not care....they just want to deliver fast and get that heavy package delivered....
two cardboard boxes and Styrofoam rarely survive the shipping
I do note the sungold power uses something to glue in more of their connections in their inverters to avoid the loose connections and they pack their inverters in wood crates to protect them...as do some of the other large heavy inverter venders.....
I just bought a set of 4 like new tires for 50 bucks>>>> i just have to do the muscle to get them changed...😢😢.to replace the car trailer tires....penny pinching in this day of hyper-inflation....🤔🤔
have a great Friday.... the weekend is almost here...... 😎
one high voltage (240 volt) ipanda solar charge controller and one Sandi 25k high voltage LF SP PSW inverter
Ipanda galaxy b240 is the high voltage solar controller mike g use . I am watching more of mike g youtube and engineer 775 youtube of the HF 8500 dollars inverter . I watch all of Sean youtube and see how stress out he is and want take a cruise to the Bahama .

Jack Rickard of evtv motor werks had a high voltage 30kw Sandi inverter with tesla car batteries and he predicted the 12kw type 48 volt would not be around in 5 years because the voltage was too low and the amp draw was not practical for a whole house inverter
Sandi is testing 800v DC inverter according to latest Sandi youtube video and will custom build LifePo4 battery bank for the high voltage because of the danger of fire . They will now also custom build 12 kw inverter for off-grid and RV so probably 48v DC . IT is the size of the Sigineer 12 kw 48v DC inverter .
custom build LifePo4 battery bank for the high voltage because of the danger of fire .
I guess people are moving away from lithium ion batteries because LiFePo4 batteries don't combust so easy.
