Enphase also demonstrated a 640-watt dual-module commercial inverter and a solar plus storage package for two solar modules on its analyst day.

Enphase is making money, has beautiful gear, and may just stand idly by. The company hosted institutional investors and financial analysts in its annual analyst day speech.

The company pointed out that the 2019 full-year revenue is expected to be 619 million U.S. dollars, and operating income is 122 million U.S. dollars, an increase of 96% and 495% respectively year-on-year. Enphase hopes to expand its business to 8 other European countries in 2020, doubling the continent's revenue this year.

Enphase expects the global residential "available market" (SAM) to grow from US$2.5 billion this year to US$4 billion in 2022. When increasing residential storage, small commercial solar, off-grid solar and storage, the company expects its SAM to reach US$3.3 billion to US$12.5 billion by 2022. Wood Mackenzie Renewables & Power estimates that so far this year, 19% of residential roofs in the United States have been installed with Enphase products.

Enphase will increase its Mexico facility from 500,000 units per quarter to 1 million units, reaching a quarterly capacity of 3.5 million micro-inverters and 120 MWh of energy storage by the fourth quarter of 2020. The company estimates that it will spend $25 million in capital expenditures to achieve this goal.

The main components installed by Enphase are the micro-inverter on the back of the module and the IQ combiner that connects the wires of the module together. The complete Ensemble 2.0 kit includes IQ8 inverters and IQ, as well as Enpower switches between the home and the grid, and energy storage solutions directly connected to the switches (beyond the main switchboard). All items are connected wirelessly.

Enphase talked about three-phase solar inverters focused on the commercial market. The device has a rated power of 640Wac and can handle two 400W solar modules. Enphase analyst TJ Roberts suggested that a 3.08A unit of 208V may cost US$100-150 (15¢-23¢/Wac) each.

Finally, the company showed off its "Ensemble in a box", which allows two solar modules to be connected to an enclosure containing energy storage, inverter and power plug. The company pointed out that the hardware's focus on energy poverty is a real social challenge for the Indian market.

Enphase said this is a $4 billion opportunity by 2022. Among them, US$2 billion is used to support the water pump market, US$1.5 billion is used as a stand-alone system, and US$500 million is used to alleviate extreme high temperatures.

I installed an 18 kW Sunrun system in December 2015 and it was working fine, but when I asked about the inverter’s ability to operate when the grid failed and the inverter manual, the salesperson didn’t tell the truth (or maybe he just didn’t know ) Did not tell the truth about being able to monitor the panel without using the Internet. I have a 10 KW inverter and a 5 KW inverter. When the grid fails, neither of these inverters will allow me to obtain energy from the array. I have a 20 KWhr lead-acid battery pack that can be used to store energy and provide energy when the grid fails, but is there an inverter or system that can provide energy for existing panels (with optimizers) and inverters for Can I get the energy from the array when the grid goes down?

Tesla Powerwall can meet your needs.

The new generation of Enphase products will be able to do this.

When I asked Sunrun to install our solar power, I questioned whether we were powered off and whether the panels could provide power within the time they could provide. The answer is no, because power must be removed from the grid, so there will be no power interruptions that interfere with maintenance work-a safety issue. They don't provide any kind of "switches" to let you just redirect power to your home...just like you do when you connect a generator. When Brightbox or Tesla Powerwall becomes more mature, I hope we can get more backup power.

Grid isolation is the problem, and it can be solved in many different ways. As one of the most expensive ESSs, Sonnen ecolinx can be set up as a smart system, using the on-board Radian 48VDC inverter to power the smart circuit breaker circuit, which can be isolated from the grid and power some key home circuits for hours or days , Photovoltaic panels that use solar energy to power critical circuits.

The downside is that many systems install string panels with a DC bus voltage of 300 to 400 VDC into grid-connected household inverters. When the grid fails, the grid-connected equipment will shut down. At present, I only know that two battery packs can be used for "high voltage" DC bus. TESLA and LG Chem can address buses within the "nominal" 350VDC range. Many other ESSs are based on 48VDC. The owners believe that what they get is the Kludged together solar photovoltaic system. When there is a problem, it will be a maintenance nightmare. Only one inverter system can be set up as a grid-connected, grid-connected backup battery, or as a backup battery with the same inverter unit. Schneider XW6048 can accomplish all three tasks through (appropriate) programming and electrical isolation technology. Another technique is to disconnect the solar photovoltaic panels and connect to an independent off-grid battery support system that supplies power to the secondary critical circuit boards. The key circuit boards will always turn off the solar photovoltaic, batteries, and inverters. (IF) The off-grid system fails or needs maintenance interruption, and then the transfer switch can bridge the primary/secondary CB panel to operate on the grid power supply.

When you say optimizer, I assume you have a Solar Edge system. If this is the case, you can convert one (or two) inverters to a StorEdge inverter rated at 7,600 watts AC. The problem is that the inverter is not suitable for your low-voltage lead-acid battery pack, but it can be perfectly matched with the LG Chem Li-ion 10 kWh battery pack. The StorEdge inverter has 2 AC connections and an internal transfer switch, so when there is a power failure, you will not feed back to the grid, but only supply power to your sub-panels.

For Enphase, Ensemble-in-a-Box can be very large. It actually contains an IQ8 with BMS for the battery, and then (2) IQ8s for each solar panel, wow! What a great speaker! Forget the Indian market... take it to any American construction site, campground, shed seller, outdoor activity, etc., and you can sell it. The utility company will be screwed up. The new war slogan will be: We don't need your damned (expensive) power!

Use 3kw Honda inverter generator and manual transfer switch to fool the inverter. Make sure to disconnect the grid. Therefore, manually change the switch.

To build a home in Roatan Honduras, I am looking for a solar company from start to finish to power it away from the grid. Sufficient power is needed to run everything and central AC power. Any suggestions and prices?

I am always surprised by such discussions and system diagrams because they do not include EV charger + EV storage to the system connection. Most residential battery storage is sized and designed to flatten the duck curve and provide backup for short-term (hours rather than days) outages. In northern California, the biggest problem is the shutdown of public safety power for multiple days during the wildfire season. For this, you need a very large battery, just like your Tesla parked in the garage. Most electric vehicles used for daily commuting and daytime work may return to the garage with 60% or more electricity. That is a lot of emergency backup power. It may be enough to run the blower on your refrigerator, LED lights, and small room air conditioner or gas FAU for a few days. These residential systems do require full EV integration, not generator connection. Who if they drive an electric car, they want to maintain and store the fuel for the generator in their heads; it makes no sense.
