12 Apr New Delta inverters H8E & H10E Launching soon – With 4 MPPTs
New Delta inverters – H8E & H10E
Delta inverters have been a famous name in the renewable energy industry for quite a long time, and the brand reflects trust, sincerity, modern technology, and longevity. With their active participation and constant endeavor in bringing incredible technological advancements in the field at an economical price point has given them a solid push to become one of the best in the industry. They had started their journey in 1971, and back then, they specialized in reactor control systems. After which, they entered the renewable energy sector in 1999 and began manufacturing the esteemed Delta inverters.
With many awards and badge of honors bagged by the Delta, they have also acquired fame in the R&D sector. They are known to be very meticulous and rigorous about quality testing, also constantly developing new technology to reach new heights of efficiency. And, the new models H8E and H10E are phenomenal reflections of such dedication.
Description of Delta H8E & H10E inverters
Delta H8E & H10E single-phase inverters are the new brainchild of Delta electronics, which was just recently announced late last year. Since then, it has created a massive buzz because these inverters are no ordinary ones. They feature not one, not two, but four Maximum Power Point Trackers (MPPTs). MPPTs are remarkable technology whose application is to make a solar panel work at its peak efficiency.
Individual solar panel without MPPTs tends to lose efficiency in regard of converting sunlight to actual DC energy. This happens due to the sunlight not being consistent at all times of the day and shading issues. And this is where MPPT comes into play. This technology pinpoints the Maximum Power Point (MPP) at which the solar panels are the most efficient and locks the MPP until the variables change, in which case the MPPT works to find a new MPP. In simple words, MPPT is a technology that helps solar panels to operate at peak efficiency regardless of any interrupting factors.
And the new Delta H8E & H10E inverters have 4x MPPT to maximize the benefits.
But, to our utter surprise, that is not the only spectacular attribute they feature. There is rather a much exciting secret which has been revealed recently. The new Delta H8E & H10E are hybrid inverters. This piece of information has taken over the industry by storm. Yes, the new Delta inverters are hybrid inverters meaning, they do not need an extra inverter to be storing energy in the battery in the event of a power outage.
To illustrate on the topic, here is a breakdown of what hybrid inverters are, and why they are a huge deal. A hybrid inverter, unlike any other inverters, gives you an option to either install the battery at the time of purchasing the inverter or later. It not only draws power from the solar panels to run the appliances with AC current, but also, it charges the battery by converting AC to DC. Once the battery is fully charged, the MPPT detects it and send the excess power in the form of AC to the grid using charge controller. Amazing, right?

A traditional inverter does the job of converting Direct Current (DC) to Alternating Current (AC) to use the regular household appliances because they run on AC current. Pairing up a conventional inverter with a battery system later on will require one to get a separate inverter to convert AC to DC current for the battery to store and release electricity for later usage, or vice versa. If one chooses to install a hybrid inverter, installing a separate battery inverter won’t be necessary as it can do the job of both. Hence, the hybrid inverters are superior in the category, and the new Delta inverter features this specification.
And the best part is, previously, the hybrid inverters used to set one back by quite a lot because it’s expensive. But Delta electronics decided not to price these inverters exclusively for their hybrid features; rather, the price point will be similar to regular inverters, and that’s a great news. But to give you an idea, it is estimated that, the H8E can cost you around $2,400 and for the H10E, $2,539. But it is only and estimation, if you are interested to consult a solar specialist and know everything in details, please contact Cyanergy.
Plug and Play Battery System
The new Delta BX 6.3_DD is a DC-coupled battery that has been built to work with the brand new H8E and H10E hybrid inverters in a ‘plug and play’ layout. This brand-new battery can work hand in hand with these models without any additional interruption. It offers a charging/discharging power of almost 3KW; also, a 6.3kWh of storage capacity, making it an outstanding performer. The model BX 6.3_EX can be extended with this battery as they have a crucial similarity. They both incorporate Samsung’s 41J module comprising of 2170 format cells.
Additionally, the BX6.3/12.6_AC100 series is going to be a Li-ion battery, which is highly popular for its energy-to-weight ratios. Also, it loses charge slowly while not in use. The master BX6.3 AC battery can distribute up to a continuous 4.5kW if paired with a BX6.3-EX (Extension) battery. Furthermore, in this scenario, the storage capacity increases to 12.34kWh, which is excellent.
Additional information that Delta electronics themselves quoted are as follows
“The system is ‘grid-forming’, being that it supports AS4777 compliant inverters during a grid failure, and we are currently testing third-party inverters to confirm their operation,” said Delta Electronics’ Shane Arnold. “If paired with a Delta inverter, we can directly control the ramping during grid failure at a faster rate than AS4777, which provides much less throughput on the battery.”
ATS Box for Extended Critical Capabilities
Automatic Transfer Switch (ATS) is an effective and intelligent power switching device that can enable the solar panel to power critical loads in a grid outage. This potentially makes the whole system a lot safer and efficient. This is a surprising new feature offered by none other than Delta with their new inverters, which are about to hit the market soon.
