Solar Inverter Buyer’s Guide 2022

The 2023 Inverter Buyer’s Guide is now available
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.
The 2023 Inverter Buyer’s Guide is now available
“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

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.
Hybrid: 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.
Hybrid: H5001
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

Sunny Highpower PEAK3 FLEX
The Sunny Highpower PEAK3 FLEX US-21 (PEAK3 FLEX) model delivers adjustable AC outputs for power, current and voltage. The PEAK3 FLEX can be tuned to match older inverters that might operate at now uncommon voltages, like 385VAC or 400VAC, thus enabling customers to leave the transformers in place and avoid costly or time-consuming studies. Similarly, the AC output current can be adjusted to help customers avoid replacing AC wires and OCPD equipment.
Adjusting the AC Voltage downward also widens the DC operating window of this 1500VDC inverter, so the PEAK3 FLEX can repower older projects with central or string inverters that were built at 600VDC or 1000VDC. Once field commissioned to the desired AC output values, the UL label will be completed to match, and those parameter settings are lockable behind OEM password protection. The flexibility in design, capacity and capability makes the Sunny Highpower PEAK3 FLEX the perfect inverter solution for repowering projects.

What’s new? SolarEdge recently launched the SolarEdge Home battery, a 10kWh battery that has 94.5% round trip efficiency and allows up to 3 batteries to be installed on its Home Hub inverter. Additionally, SolarEdge has announced several new features in its mySolarEdge app, including Weather Guard, a feature designed to fully charge the battery when a potential severe weather event is detected nearby. Looking forward, SolarEdge will release its new S-Series residential Power Optimizer, which features SolarEdge Sense Connect, a step change in arc-fault detection and prevention. In the C&I space, SolarEdge is looking to bring to market solutions that serve large-scale and community solar applications. S-series Power Optimizers implement condition monitoring features, or the ability to identify changes in a PV array that could indicate a developing arc fault.
TerraMax Inverter
The new SolarEdge TerraMax 330kW Inverter is designed to maximize energy production for any project terrain and for overcoming challenges posed by shading and uneven terrain on community solar ground mount sites. In addition, it is the ideal product for agri-PV, small-medium utility-scale projects and floating PV. It delivers more energy with 200% DC oversizing for up to 50% less Balance of System (BoS) costs (Based on comparisons using HelioScope on 8MW projects and typical string inverters. Numbers can change based on project characteristics).
In terms of power, this inverter helps ensure continual peak performance with an integrated PID (Potential Induced Degradation) rectifier and boosts energy yield through DC-optimized technology with multiple MPPTs.
To save on BoS costs, the inverter works with fewer and longer strings on up to 80 modules, and further streamlines by providing higher power through fewer units. The SolarEdge TerraMax inverter also speeds up onsite work with a topology feature that places the inverter in a central location alongside distributed, multiple MPPTs in the array. These factors can reduce labor, installation time and material cost with virtual central topology and single DC input architecture.
Finally, the TerraMax Inverter also simplifies operations & maintenance, reducing unnecessary truck rolls with granular, module-level monitoring, and reducing schedule risks and maximizing system uptime with automatic alerts and remote troubleshooting capabilities.
Key specs:
- kW range: 330kW
- Operating voltage range: 587-759 Vac
- of MPPTs / MPPT voltage range: 12.5-105 Vdc
- Max / CEC efficiency: 2/99.0%

H1300 Power Optimizer
Supporting high power 650W modules, SolarEdge H1300 Power Optimizers enable modules in the array to work independently. The underperformance of one module will not affect others in the string, eliminating mismatch-related power losses due to shading, soiling, or aging, enabling higher overall energy production.
The H1300 also helps to harvest more energy from bifacial modules by mitigating electrical losses caused by the varying ground albedo, shading, obstructions, or other rear-side factors. Further, inter-row shading losses are minimized with module level MPPT. Plus, up to 80-module string length is supported, resulting in fewer strings and enabling up to 50% BoS savings when compared to traditional string solutions.
Additionally, the H1300 helps keep production rolling with granular and continuous module-level data monitoring for EPCs and O&M personnel. It tracks system performance and helps to pinpoint & resolve issues remote or onsite using our Monitoring Platform.
HomeHub
The SolarEdge Home Hub inverter’s industry leading 99% weighted efficiency paired with its ability to DC oversize up to 200% allows installers to install more power, increase system ROI, and better meet the increasing energy needs of their customers. Additionally, the DC-coupled Home battery offers installers the ability to install the inverter, battery, and EV charger on a single breaker which enables faster installation both at the time of install, as well as with future additions, with fewer main panel upgrades. DC coupling allows for inverter, battery, and EV charger to be installed on one breaker, resulting in fewer main panel upgrades, and lower installation costs. All of this paired with a standard warranty of 12 years extendable to 25 years, integrated arc fault protection, and in app features such as Weather Guard, enables installers to offer their customers increased peace of mind and reliability.
