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)
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)
