3kW 120V AC output,
capable of split phase 240V output with 2 or more units
80A MPPT Charge Controller (up to 4.5kW of Solar ) at panel voltages between 120Vmp to 250V open circuit
48V battery is OPTIONAL, in other words, it can run with nothing more than some solar panels connected. bear in mind, solar energy can fluctuate easily with shadows, clouds, bird poop etc. so be prepared to have some interruptions in supply if your load is higher than the solar input.
Very cool usage for barns, well pumps, animal water heating systems for winter etc.
Some of our customers in AZ use them for directly powering air conditioners during the day.
Or use Utility power as a backup, Solar will offset utility power usage with or without a battery.
Did you know that Growatt is the only Chinese inverter manufacturer that received the "All Quality Matters" Award by TuV Rheinland Germany.
NOTE: These units do support the Growatt Batteries and most other BMSs supprting CANBUS or RS485 Growatt protocols If not using battery BMS connection -choose battery type "USR" or USER, and enter in your battery suppliers (Bulk, Float, Low Voltage Cutoff, and Charging Amps) -
Another note, there seems to be a lot of confusion about BULK and Float Charge Setting.
Bulk Charging, is usually the 90 or 95% or less than MAXIMUM Battery voltage, this is where the fast charging mode occurs. (usually around 57V) (contact your supplier)
Float Charging (holding charge), is the resting or nominal voltage of the LiIon or LiFePO4, when it is fully charged, but now in a resting state with no load, usually around 52Vto 55V for LiFEPO4 (contact your supplier)
Low Voltage Cutoff, this is the voltage the inverter needs to turn off before depleting the battery - you want your inverter to shut off BEFORE your battery to dies, or the BMS to disconnects (usually around 48V or whatever the 20% charge voltage is)
This unit is not a knockoff like (POW EASUN etc.) This is a very well built / designed product, otherwise we wouldn't sell or support it.
Supplied by a top tier support outlet here in the USA, (Utah).
Parallel Kits already built in,
super quiet operation.
Very detailed Color LCD display
5-in-1 unit. (Not Grid Tied - no feedback, only Grid assist - the load gets switch over to grid when all else fails)
1) 3000 W Pure Sine wave output expandable up to 6 units (18 kW)
2) 4kW MPPT Solar Charge controller
3) 60 A 48V Utility Battery Charger (In case your battery level falls below your setpoint)
4) UPS function, wire it to the Utility power, if battery power is too low, the system automatically switches the load to Utility power
5) Single 120V 60Hz , Split phase (120V - 0 - 120V ) and 3 phase capable (includes parallel board for each unit)
6) Pure Sine wave output expandable up to 18 kW (single or Split Phase configurable - will need to all be connected to the SAME battery, make sure its large enough to handle the load for the time - usually 2 days or more)
Growatt is well known brand amongst solar professionals.
WARNING. with these (all models with more than 145V) high voltage MPPT input models, DO NOT ground the PV+ or PV- inputs, do not share panels with other inverter MPPT inputs.
Each MPPT Input needs it own solar panel array , do not share common wires between arrays for different MPPT input.
Keep it simple, One Inverter, one solar panel array (obviously the panel aluminum frame must still be grounded to conform to safety standards)
Not following these simple rules can cause damage to your inverter / pair of inverter.
Hybrid Power System
This is a multi-functional off grid solar inverter, integrated with a
MPPT solar charge controller, a high frequency pure sine wave inverter
and a UPS function module in one machine, which is perfect for off grid
backup power and self-consumption applications. This inverter can work
with or without batteries.
Add PV modules, generator, or utility grid, all or None.
Please consult with your system integrator for other possible system architectures depending on your requirements. The WiFi /module is a plug-and-play monitoring device to be installed on the inverter. With this device, users can monitor the status of the PV system from the mobile phone or from the website anytime anywhere.
Rated power 3KW, power factor 1
MPPT ranges 120V~250V, 250Voc
High frequency inverter with small size and light weight Pure sine wave AC output
Solar and utility grid can power loads at the same time With CAN/RS485 for BMS communication
With the ability to work without battery
Parallel operation up to 6 unit (only with battery connected) WIFI remote monitoring (optional)
