    Rosen Solar from Alibaba, anyone have experience?

    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.

    Rosen Solar from Alibaba, anyone have experience?

    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...

    Rosen Solar from Alibaba, anyone have experience?

    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 ?

    Rosen Solar from Alibaba, anyone have experience?

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

    Rosen Solar from Alibaba, anyone have experience?

    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...

    MPP-SOLAR LV6548

    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.

    MPP-SOLAR LV6548

    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...

    220V Euro Inverter to power 240V US compressor/air conditioner

    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.

    Mini-split Coolant Line Question

    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...

    Mini-split Coolant Line Question

    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...

    MPP LV5048 weird activity

    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...

    MPP LV5048 weird activity

    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...

    lv5048 inverter to utility panel

    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...

    Connecting two TOTALLY different batteries and Panel - Problem?

    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...

    Mini-split Coolant Line Question

    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...

    Mini-split Coolant Line Question

    The DIY ones here mainly MR COOL brand should NOT BE VACUMED AT ALL ! They have FREON SEALED IN THE LINESET. The ones that people just choose to do as DIY install (almost all others) come with generally enough freon in unit for up to 25 foot linset. Its possible if you use a 15 foot linset...

    mpp lv5048 questions

    Yes and several things to consider also. This is correct for the Grid bypass INPUT but for the OUTPUT from the Inverter (MPP LV5048) the following applies . If you parallel the units you would need to combine the output of both inverter then make ONE connection to main service box UNLESS you are...

    Here is a You tube video from DMI about the parallel setup of the MPP LV5048 s and I am sure he has another about the wiring predating this one.

    mpp lv5048 questions

    I totally agree the LVX5048 s would be my choice since they take 450v or so pv string and they can inject (offset blend in) power from the grid but he specifically said he had 2 LV 5048 s

    mpp lv5048 questions

    BTW the manual shows the wiring diagram though its a little confusing as to which one you need . Its the 2 phase 240v diagram for the MPP LV 5048 s and the manual is located here . Its near the end like 32 to 39 pages...

    mpp lv5048 questions

    NO !!! The LV6548 is NOT inherently a 240v US split phase unit. First you MUST have 2 to even get split phase from the LV6548 s. Ifr you notice on that video Will connects ONE of the LV6548 s to EACH LEG of the main lug box to get 240 split phase then as with both models you need to program it...

    DEYE Inverter UL Listed available in US

    Yeah , I dont see why there aren't LiFe Po4 cells made here . It seems as though with advance of solar etc and this being a vital supply for that including maybe military use that there would have to be US providers for Military contracts etc. I can see at least a few whole Military Bases being...

    DEYE Inverter UL Listed available in US

    True but HVAC is my main need the other 120 loads I could run with my Honda 2000 easily and fairly economically compared with large generators (especially using LP or Natural gas. Yes Solark is equal to about 5 LV6548x but with 4 you get into a lot of mounting room and lots wiring connections...

    DEYE Inverter UL Listed available in US

    One thing Solark is probably counting on right now is the Tax credit to make them look more comparable . The fact that not many installers will use the chines inverters also helps them. The added features and long warranty of the solar 12 (about same price as the 8) is one more reason BUT that...

    DEYE Inverter UL Listed available in US

    Thats my view also. If you are totally off grid it would be a good idea to have a spare inverter for emergency use. That is one reason I chose not to get the LV6548 s . I would need 2 for 240 split and felt like I needed 2 spares in the case of both originals going out at same time.

    MPP-SOLAR LV6548

    I thought about doing the same thing with the LV6548 s but would need 2 and would want to have a backup so 3 but then if had problem it may affect both so 4 and use 2. (actually wanted 2 of the LVX6048 but they were not going to be available for a while) I already had 1 LV5048 and had another...

    European Inverter for US HVAC/ 240v loads

    I have HVAC 240 volt unit . I am thinking about providing its power with a European MPP MG 5048 inverter that I have been using as a battery charger for panels located farther away. ( I am also using MPP LV 5048 for rest of home right no). The inverter has a 240v 60 hz setting available. I...

    Virtual Critical Circuits Panel: The Span Panel

    They do have their own specs and some differences from the 7.6 Deye etc but basically yes. They do however also provide good customer support and make good on their guarantees etc . It also seems they will be in business for a substantial time period. The inverters are generally available...
