SKU: 6000T-MPV Category:


We no longer sell any units MPP/ Growatt or any other brand having (built in) or requiring an Auto Transformer on the output, If the inverter is in bypass mode, any Grid Imbalances will be fed through the inverter Auto Transformer

In some cases up to 60A has been seen

Even worse when more auto transformers are put in parallel, with some models.

This is for the MVP Model 250V PV INPUT,
Whole (small) house power module, all in one not Paralell-able –  Comparable to the MPP Solar LVX6048 (450V PV Input and is parallel-able)
48V 6KW Growatt SPF 6000T MVP DVM Low Frequency Split Phase 120V & 240VAC.
Supplies a massive 50A output at 120V , 25A at 240V
USA Breaker Box compatible, L1 –  N –  L2  (120 – 0 – 120V)
Whole house power at 6kW
a massive 18kW surge capability
Wifi Module – Growatt Shine Link for your Iphone / Android available in our store
Grid Assist Feature bypasses the inverter in case of overload or programmable UPS function, or low battery
60A Utility/Generator Battery charger  (60A x 48V = 2800W at 240V Utility supply)
Generator Dry contact start output
Generator / Utility needs to supply 240V to charge the battery
Solar Panel Connection
80A (5kW) Solar MPPT Charge controller (60V to 250Vmp)  –  Maxiumum VOC is 250VDC, but remember the lower your panel voltage the less power the MPPT can harvest
Number of panels you can connect = 5000W / [your panel wattage] – example 5000 /345W = 16 panels , 5000 / 240W = 22 (21) panels etc
Basically 230V (To be safe) / your Solar Panel VMP voltage will give you the number of panels you can connect in series
if your Solar panels’ Vmp (Voltage at maximum power – the lower of the two numbers on your panel spec) (Not Voc) voltage is between 38.3 V and 57.5V, you can connect 4 in series with matching parallel strings to add up to the number of panels as in formula above. 16 x 40V panels would be connected in 4s4p
If your Vmp is between 28.75V and 38.3V you can connect 6 in series with matching series strings connected in parallel to add up to the number of panels as in formula above.  example: 18 x 35V panels would be connected in 6s2p
If your Vmp is between 17V and 28.75V, then 8 in series with matching series strings connected in parallel to add up to the number of panels as in formula above. example 48 x 20V panels(maybe 100W) would be in 8s6p (48 panels)
Can be shipped via Fedex Ground  to your door as it weighs less than 150 lbs  (105 lbs)
Breaker Recommendation:
AC Breaker Recommendation (double pole 240V)  8AWG, 80A  (Input & Output)
PV Input DC breaker (10AWG)= Total Solar Panel Watts / Solar Panel Array Voltage x 1.25  , example 2 parallel strings of 10A output panels will be around 20A
Battery , 6000W / 48V = 125A x 1.25 = 150A DC Breaker to battery bank. (2 x 3 AWG)
Battery recommended to be no less than 250Ah (12kWH, can be Lead Acid, AGM, LifePO4, Li-Ion etc  any battery between 40 to 60V DC).
Battery is required to operate!
There is no maximum battery size recommendation  (Ah)
If more solar power is needed, simply purchase a separate solar charge controller(s)such as the PCM60x to add as much solar power as you want

Utility/Generator Charger tips:

The generator charger is a different beast to the solar charger. (Does not utilize the Bulk and Float Charge settings)
It works on a float valve type principle. (triggers when battery voltage drops below that on setting 12 – set the voltage higher than current battery voltage to start charging right away)
Stops charging from Generator when setting 13′ s voltage is reached
Will not start charging the battery again until it drops below battery voltage – in setting 12.

Setting 01 set to SBU to activate setting 12 and 13.
Setting 02, is the Max charging current from Solar + Utility/Generator
Setting 11, is the Maximum Generator/Utility charging current @ your battery voltage (not at 120V)
Setting 14, make sure this setting includes the option to charge from utility/generator (see manual)

Note, setting Setting 11 too high for your generator may cause your generator to falter at startup, and cause the Inverter Charger to lose synchronization with the Generator (58 to 63Hz), if in doubt start small, and work your way up.

Auto Start Function for the Generator  (optional)

Inverter Dry Contact relay output triggers according to the above settings, when battery charge is requested  (Normally Open/Normally Closed  Contacts)  ,  it is a simple 2 wire system, your generator will need to be a 2 wire start system  (the generator needs to start itself when circuit is closed, and stop when circuit opens)  – this can be wired directly to the dry contact input on the inverter

Hint, use this dry contact relay output like a switch to turn on a light or a buzzer  (wire it in series with the battery , or inverter output to the light/buzzer ) to let you know the battery is low, and needs charging (manual notification)

If you have any questions, feel free to reach out.

  1. Joe Boike (verified owner)

    Awesome, very heavy, loud fan @ full power, easy to hookup and operate, performs as advertised and beats the high frequency inverter I had by FAR. Split phase is great for running my mini-split 240v A/C and 110v appliances. Little hick-up getting account registered with Growatt Server but works great on My PC and Android, has tons of information available. 5 stars isn’t enough – service after the sale from Watts247 was fast and effective, was able to get connected WiFi the same day of installation, thanks Ian Roux.

    I have nothing but good experiences and good things to say about Ian Roux and the wide range of innovative affordable solutions to create power from the sun.
    As an HVAC/Solar contractor the path became clear when mini splits hit the scene and using MPP Solar products or Growatt products we are converting entire homes from central ac to mini splits and powering them all with a small inverter.
    I’ve found these systems to be incredibly reliable, the data that it provides has allowed us to monitor the systems performance on a phone app or desktop and graph the ac usage over solar output and using this knew we had to add two more panels to better meet peak demands during the hottest days.
    Combine the features of the products with Ian’s 6 star support and you will be immediately confident you are shopping at the right place at the right time for exactly the right product.

    Customer Interface:
    The systems we installed have an intuitive, have a background lit LED data window on the
    With the optional WIFI interface we can monitor the systems remotely which is an added
    benefit to the end user.
    what the data provides takes the mystery out of the system for the end user
    Warranty issues:
    One of items we purchased had a defect and was covered under warranty.
    The replacement part was back in our offices within a week.
    Everything has always arrived intact, ready to run.
    Inverters, controls and solar panels by the pallet all arrived on time
    and undamaged.
    Buying a pallet of panels (25) at a time from Ian is the best deal I’ve found

    I installed the Growatt SPF 6000T in our off-grid home in Baja, Mexico a couple months ago. We have 4500W of panels, and 8 12V 250A-hr lead-carbon AGM batteries, two strings in parallel giving 48V and 500 A-hr.

    So far I love it. I have just installed two mini-split air conditioners in the house. A 1-ton unit keeps the battery/control room at 75F (with window to the bathroom adding some cooling to the house). Then a 1.5 ton unit in the living room. We turn on the air conditioners at about 8am and run them all day. PV powers the house loads and also charges the batteries until around 5:30pm when we turn down the AC, and both are off by 7pm. With a well insulated house we keep the ceiling fans running all night and the house warms to about 84F overnight, which is totally tolerable with a ceiling fan over your bed. So far so good!! It will get hotter here for July, Aug, Sept so we will see how it keeps up – I’m still improving on house and battery room insulation. No AC needed for the other 8 months of the year, need to find some other way to use the excess power – maybe an electric motorcycle, haha 🙂

    The Growatt ShinePhone app is not designed with the best user experience, but once you get comfortable it provides and excellent instant check on your phone on how your system is doing at any time. Their website dashboard is much better with nice graphs of power usage, battery status, PV, etc – here’s a web screenshot from yesterday, and a phone screenshot just now.

    Anyway, so far so good – very happy with this setup and the Growatt. And watts247 support when needed has been amazing!
