Solar Inverter Buyer’s Guide 2022

Solar Builder Inverter Buyer's Guide

The 2022 Solar Inverter Buyer’s Guide shows an incredible number of options to meet any project needs. Microinverters that can handle 880 Watts or enter a grid-forming mode to power a home in an outage with just PV. String inverters with more energy storage versatility and better roundtrip efficiencies. There’s a lot to digest below, so before we get to what’s new from 15 manufacturers, here is some advice on what to look for in an inverter spec sheet.

“A key part of an inverter spec sheet is which MLPE the inverter is compatible and certified with for Rapid Shutdown (PVRSS). It is important to identify the certified components prior to installation in the field to ensure NEC compliance. Not all inverters and rapid shutdown system pairings meet the 30V in 30 seconds requirement.” – Sarah Ozga, Product Manager, Tigo Energy

“Pay close attention to the number of units per branch. Fewer units means improved reliability by reducing potential points of failure, but also means fewer units for installers to purchase, stock and install. Also, compare the MPPT voltage range. A wide peak power tracking voltage means a microinverter can turn on earlier and stay on later.” – Jason Higginson, APsystems

“For microinverters, the actual expected AC power output and elimination of power ‘clipping’. With modern microinverters, it is unnecessary to tolerate any clipping with new higher Wattage PV modules. The industry norm has been lazy on this topic – it’s possible to eliminate clipping and stop wasting energy harvest and kWh.” – Ed Heacox, CEO, NEP

“While not explicitly mentioned on a datasheet, the number of hardware components an inverter requires is a spec that installers should pay close attention to. Modern string inverters, for example, have many integrated features such as software-based shade mitigation, multiple Maximum Power Point trackers (MPPT), and monitoring. This integration reduces the number of components in a system compared to technologies that require microinverters or DC optimizers on each solar module. The reduction in the number of components decreases the costs for hardware and labor and makes a system safer and more reliable because this system has much fewer potential points of failure, e.g., DC connectors.” – Richard Baldinger, Fronius

“Inverter spec sheets are reflective of an increasingly homogenous data set that doesn’t always reveal the short and long-term impacts system owners and installers can expect. In fact, we feel that the most important considerations are those not found within the confines of a traditional data sheet. Installers should pay attention to the longevity of a company, how their products are manufactured and what quality assurance measures are taken to ensure long-term, trouble-free performance. Risk reduction is critical in maximizing system performance, and a data sheet is just one piece of information that installers should evaluate when selecting an inverter.” – Brad Dore, SMA

“For off-grid inverters, two key specs and one key feature are often overlooked: 1) DC operating voltage is a common shortcoming, since off-grid voltage and battery swings are wide; 2) Self-consumption is important, since it affects system efficiency; 3) Fanless design is something to look for, since many inverters require cooling fans and they are sometimes the weakest link. Fans consumer power and represent a parasitic load (degrading efficiency). They have moving parts and can (and often do) fail. And they can shorten the inverter’s live because they pull in dust, dirt and debris” – Bill Mellema, Product Director, Morningstar Corporation


GoodWe

What’s new? GoodWe A-ES Hybrid inverters are in stock and ready for delivery. The GoodWe A-ES hybrid inverters are also available via GE as the GE Solar Inverter.

APSystems

What’s new? APsystems has launched the new DS3 microinverter series, designed to accommodate today’s high-capacity PV modules and create a strong competitive advantage for installers. The DS3 series covers a wide variety of PV module types and sizes, installs faster and is the most powerful dual microinverter in the world. Fewer units on the roof, and fewer PV modules required for the same output as competing systems, puts more money in installers pockets. The DS3 means the maximum solar power output for homeowners and higher profits for solar installers.

aps-DS3

1. The DS3 is the most powerful dual microinverter in the world. Three models cover most all panel types, sizes and capacities.
2. Far less equipment and at a lower cost. Competing systems require up to 3X the inverters and up to 60% more PV modules on the roof to hit the same output.
3. It installs faster than conventional microinverters and is simple plug-and-play.
4. Built-in Zigbee 2.4GHz wireless communication creates a mesh network for high-speed data transfer.
5. Fully NEC 690.12 and UL 1741 SA (CA Rule 21) compliant.

cps-america-logo


What’s new? Chint Power Systems America is introducing its 250/275kW, 1500Vdc three-phase string inverters for North America. These high-power inverters are designed for ground mount and utility-scale applications. Available with either 36 fused or 24 unfused PV string inputs and 12 MPPTs. At Intersolar, CPS showcases these as part of a new Inverter Cluster, which combines three 275-kW inverters with one 800Vac Fused Disconnect, simplifying installation, and providing a cost-effective mounting solution.

CPS Ground Mount Installation

The 275kW high power CPS three-phase string inverters are designed for large utility-scale ground mount applications. High efficiencies, wide operating voltages, broad temperature ranges and NEMA Type 4X enclosure enable this inverter platform to operate at high performance across many applications. The 275kW inverter includes touch safe DC fuse holders for added convenience and safety. CPS will accompany the 275kW inverter with an 800Vac Balance of System offering for optimized system designs.

  • 12 MPPTs with 36 fused inputs for maximum flexibility
  • Full power capacity up to 42oC
  • Wide operating and MPPT voltage ranges

darfon-electronics-corp-vector-logo

What’s new? Darfon Solar will be launching its new out-door rated energy storage solution. The H7 is a hybrid inverter and the B17 LFP battery. The H7 can support loads of up to 7.6kW. The H7 can also be both AC-coupled and DC-coupled at the same time, so more solar panels can easily be added to an existing system. The B17 is a 17.5kWh high-voltage LFP battery. The high voltage design increases the conversion efficiency, lowers the current, and reduces the cable thickness.

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
  • Compatible with various battery chemistries
