Darfon

What’s new? Darfon will be launching a new monitoring app for its hybrid inverters in Q2 of this year. While designing the app, our main focus was to make it easy-to-use, expand functionality, and be aesthetically pleasing. I believed we achieved that and am looking forward to the launch and reaction from homeowners and installers. The cool thing about our monitoring service is our hardware’s connectivity options. Our latest data logger used in conjunction with our hybrid inverters, can connect to the internet via a LAN, WiFi or 4G cellular connection.

H7

The H7 hybrid inverter is sold with the B17 LFP battery. Since they are both out-door rated, they can be installed outdoors for easy access. Since Darfon makes both the inverter and battery, we can gather data to monitor and troubleshoot both products. The H7 comes with an external wireless display to control and see the current status of the system from inside the home. Like out previous hybrid inverters, the H7 is transformerless and has breakers, disconnect switches and generator support circuitry.

  • Support loads of up to 7.6kW
  • Grid input and output can be as much as 9.6kW
  • Up to 12kW of PV with 4 MPPT when DC-coupled or 7.6kW when AC-coupled
  • To be installed with the B17, a high-voltage LFP battery
  • It only weighs 86.8lb, so it can be easily mounted and installed.

H5001_DoorOpened (1)

Darfon’s H5001 hybrid inverter can be used as a string inverter. Why is this useful? A hybrid inverter is more than double the cost of a string inverter. But if you look at the system cost, the inverter is only a small portion of that cost. The batteries are the most expensive component in hybrid system. In some cases, the additional cost of the batteries is what people cannot afford. So, it makes sense to install the H5001 as a string inverter and have a system that is energy storage ready. Then the batteries can be purchased and installed down the road. The thing that installers like about the H5001, is that it is straight forward to install and configure.

  • PV Operation Voltage Range 120 to 500VDC
  • Two MPPTs
  • Output to Grid: 5000W, Output to Load: 5500W
  • SGIP Compliant

sol ark 30-60K

Sol-Ark introduced a line of three-phase hybrid inverters in light commercial 30K-3P-120/208V and industrial 60K-3P-277/480V. Both support 4 MPPTs for dc coupling, ac coupling, generators, UPS grade 200A 5ms auto transfer switch between grid/off-grid/generator, 12 parallel stacking, two independent high voltage batteries, and U.S.-based remote monitoring/control. Previously, 208V ESS applications had to use 480V inverters and massive transformers, wasting power and install time. Most previous C&I hybrids were for on-grid peak shaving or meter zeroing and lacked built-in transfer switches for grid forming. Sol-Ark 30K & 60K is an all-in-one, easy-to-install hybrid inverter for the C&I market.

  • Native 3Phase 120/208V or 277/480V without a transformer
  • Built in 200A 5ms Grid/Off-Grid/Generator transfer switch
  • Built in 4 MPPT’s for DC Coupling & Simultaneous AC coupling
  • Parallel stacking to 12 units
  • US based remote monitoring/control
