A 90 Amp passthrough would be very useful especially with on grid use where it would be nice to connect the inverter to the whole service panel and use the grid to get high start up power loads working then inverter will run them without soft starts etc in many cases.

That sounds really good. More and more people will be wanting to charge electric cars and using the cars designed to do so as backup batteries too. I can see 2 electric car families with one vehicle at home most of the time soaking up all the excess home PV and either swapping the stay at home...

Great to hear I could get by pretty well with 12k output but would still like to have the inverter to be able to supply a 15 kw passthrough from the grid. Do you have an idea of what the max passthrough from grid would be on the upcoming true 15 kw offering ?

Yep but I would like the 15K and use my current inverter as backup. It would only take about 45 minutes to swap out.

Yep but you can still get the single phase and autotransformers much cheaper than solar. I am interested in learning when a solar 15 K (if it is actually 15 K) will be available and the pricing. Engineer 775 recently mentioned being a beta tester for this soon. That would accomplish several...

Yes but several other 48 v inverters that are split phase 240 volt can also supply power without batteries but of course ONLY while the sun/pv power is available.

Agree the answer is No unless you have 2 24 v batteries. The problem would likely never be the startup for the inverter or a sub 1,000 watt load. You must have a 48 volt battery system though. 4 inexpensive lead acid 12 volt batteries would work but you would be limited in capacity to about...

Basically I would say that if there is no neutral wire even going to the HVAC then you should be ok to wire it as explained. Some split units (not meaning mini splits) use 240v for outdoor condenser and 120 for the indoor unit fan etc.

Yes I think Alpine sells some DIY mini splits that are rebranded for them as Blueridge and likely made by Free or Madea. I see from your signature etc that you should know !! I have done a lot of DIY including geothermal install and mini splits etc. Interestingly I and my family also own 6...

Yep wouldn't work in my area much at all due to high humidity and I suspect many similar areas. Generally a 12,000 BTU mini split once the area is cool may only use about 400-500 watts but of course that depends on the heat load of the RV. Remember you can also start with a fully charged...

I currently have 2 sets of 20 Kwhr of 56 modules of Nissan Leaf cells connected to 2 parallel LV5048 s there are two 2 gauge welding cables connecting to each of these terminals https://www.amazon.com/gp/product/B07C6483RC/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 Then the 2 paralleled...

I currently have 2 MPP LV5048 s in parallel. I have a 5 ton 2 stage scroll compressor HVAC unit that I only use in stage 1 which is about 3 1/2 ton equivalent. I know the single MPP wont start it so I obtained 2 more to use in parallel . I have only connected one more at this point . I read...

The transfer switch in the MPP LV5048 is a "dry contact" meant to signal an electric start generator capable of auto starting to start . This isnt meant to power a service panel in place of power outage. You would need a transfer or interlock switch at the service panel you wish to energize...

Personally I would not mix battery chemistries for a solar battery storage system but I know some do like David Poz with Lithium manganese cobalt and Lithium Iron Phosphate with number of cells matching as close as possible in charge parameters but you would definitely not be utilizing the...

Remember you would also have fittings and depending on the unit the lines may have 1/4 inch and 1/2 inch lines plus 5/8 inch drain line plus 4 conductor 14 guage wire plus insulation. The larger and less efficient units like anything above 12,000 BTU may use 3/8 inch and 5/8 inch copper lines...
