Growatt 48V 12000T DVM 12kW Split Phase 120V/240V output (100A at 120V ,50A at 240V) – 150V Max PV Input ( 2 x 3.5kW Mppts -7kW)
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.
Whole house power module, all in one. There is nothing quite like it on the market
48V 12KW Growatt SPF 12000T DVM Low Frequency Split Phase 120V & 240VAC.

USA Breaker Box compatible, L1 – N – L2 (120 – 0 – 120V)
Whole house power at 12kW
a massive 36kW 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
100A Utility/Generator Battery charger (100A x 48V = 4800W at 240V Utility supply)
Generator Dry contact start output
Generator / Utility needs to supply 240V to charge the battery
Solar Panel Configuration:
120A (7kW) Solar MPPT Charge controller (60 to 115Vmp) –
Number of panels you can connect = 7000W / [your panel wattage] – example 7000 /345W = 20 panels , 7000 / 240W = 30 panels etc
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 2 in series with matching parallel strings to add up to the number of panels as in formula above. 20 x 40V panels would be connected in 2s10p
If your Vmp is between 28.75V and 38.3V you can connect 3 in series with matching series strings connected in parallel to add up to the number of panels as in formula above. example: 30 x 35V panels would be connected in 3s10p
If your Vmp is between 17V and 28.75V, then 4 in series with matching series strings connected in parallel to add up to the number of panels as in formula above. example 70 x 20V panels(maybe 100W) would be in 4s18p (72 panels)

Breaker & Cable Recommendation:
- AC Breaker Recommendation (double pole 240V) 6 AWG, 80A (Input & Output)
- PV Input DC breaker (8 AWG)= Total Solar Panel Watts / Solar Panel Array Voltage x 1.25 (example 20 x 300W (37Vmp) Solar Panels = 6000W of Solar connected in 2s configuration gives 37V x 2 = 74V, 6000 / 74 = 81A, 81A x 1.25 (25% more) = 101A (or a 100A DC breaker)
- Battery , 12000W / 48V = 250A x 1.25 = 300A DC Breaker to battery bank. (3 x 2AWG)
Battery recommended to be no less than 500Ah (24kWH, 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.
