NOTE: 1 Wifi module required per inverter when requiring remote monitoring  (not required for inverter operation)

This fills a particular market niche that we just weren’t getting a product for.

Did you know that Growatt is the only Chinese inverter manufacturer that received the “All Quality Matters” Award by TuV Rheinland Germany.

Youtube incentive:

Create a video of how you installed your system

The Solar Panels you chose, and why  (Watts, Volts, Amps, Wire size chosen, length of run,  using online volt drop calculator etc). The Battery you chose, and why. Inverters menu and operation  (What mode you are using it as, and why). Load testing your system. If you have two or more units, split phase operation. Charging via generator (optional). How and where the unit is installed and hooked up.

SPF 3000TL LVM – 24P solar 3KW 24V Split phase capable pure sine wave output  (also available in 48V, 3KW), stack-able. Supports Li Ion and Lead Acid, and other chemistries between 20V and 28V.  Tesla batteries not recommended, as they are actually 20V batteries sold as 24V.  LiFEPO4 are great, so are the Nissan Leaf Li-IONS

NOTE:  These units do support the Growatt Batteries with Growatt BMS  (these will be available later on in the year),  for now, choose battery type “USR” or USER, and enter in your battery suppliers (Bulk, Float, Low Voltage Cutoff, and Charging Amps) – Your BMS will NOT communicate with the inverter

(If you want to mess with the BMS protocol to interface to your Arduino or whatever, the protocols can be found at usa-mpp-solar.com/manuals/gw)

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 58V) (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 51 to 52V 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 47V 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 LCD display
• 2 yr swap out warranty.
• 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) 2kW MPPT Solar Charge controller

3) 60 A  24V 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)
