For system integrators, the simplicity and price-performance of the Harbor 10P/15P Smart Battery set it apart from other grid-tied battery systems, said Ben Polito, Pika Energy’s President and Co-founder.

“A single technician can install and commission a Harbor 10P/15P in less than an hour,” Polito said. “Harbor is pre-wired for the Panasonic battery modules, making assembly incredibly fast and simple. Combined with our transformer-less inverter, the Pika Energy Island with Harbor 10P/15P offers a vast improvement over heavy wall-mounted battery systems and outdated multiple-inverter configurations that suffer from low efficiency, extraneous hardware and complex installations.”

Harbor 10P/15P enables customers to take full advantage of the Pika Energy Island’s built-in operational modes for solar-plus-storage. In islanding mode, the Harbor 10P/15P seamlessly powers heavy loads like well pumps and refrigerators without a grid connection, providing customers with a superior backup power system. When grid-connected, its 10kWh (model 10P) or 15kWh (model 15P) capacity provides self-supply of local loads during evening hours when energy rates are highest.

“The smartest, simplest way to build solar-plus-storage systems is by combining batteries and solar PV on a common DC bus,” said Polito. “The Panasonic-powered Harbor 10P/15P Smart Battery brings that concept to life, without compromising power output, scalability or flexibility. As solar PV adoption continues to boom, the grid needs smart, distributed storage. We’re thrilled to be working with Panasonic to offer what we believe is the solar-plus-storage solution the industry has been waiting for.”

This new solar energy busbar bypass breaker could cut install costs

While interest in renewable energy solutions such as solar power in residential and commercial settings is on the rise, and more Americans convert to electric vehicles (EV’s), one of the biggest remaining impediments is the hidden cost of upgrading the electric panel, also known as the load center or panelboard. Upgrades could be required for at least half of American households and can add thousands of unanticipated dollars to the initial purchase and investment as well as countless hours of permitting and delays to installations.

Technology innovator Q Factory 33’s energy division, QFE002, after receiving its UL 67 & 489 certifications for its B3 Bypass, might have the answer.

The B3 Bypass, the first and only commercially available bus bar bypass breaker, delivers exponential gains in backfeeding of energy from solar panels and other green energy sources, eases connectivity to electric vehicle charging stations and battery backup systems, and substantially reduces the installation cost of solar and other clean tech for residential and small business applications.

busbar bypass

Experts who have seen the unit in testing consider the B3 Bypass a, “game changer,” and have been closely monitoring its progress toward achieving it’s UL certifications. The B3 Bypass has undergone extensive testing, and, with these certifications, is now positioned to help consumers and businesses more affordably install virtually any renewable energy source.

Such UL certifications mean the B3 Bypass has met UL’s stringent requirements for Standards and Safety, making the unit ready and approved for widespread commercial use. According to the Solar Energy Industry Association, the US solar market is expected to triple in the next 5 years, and a new solar project is being installed every 2 minutes.

The International Energy Agency wrote in a 2015 report that, “Renewable energy will represent the largest single source of electricity growth over the next five years.” There’s no underestimating the impact the B3 Bypass is likely to have on such an expanding market.

“What impresses me about this solution is the simplicity of the idea for the benefit it gives,” said Dr. Clark Guest, Professor Emeritus, Electrical and Computer engineering Department, University of California San Diego. “The B3 Bypass represents one of those ideas where everyone who encoun-ters it says, ‘Why didn’t I think of that?’ It’s a missing element solution that bypasses a great many of the soft and hard costs associated with scalable energy production while accelerating exponential gains in energy output,” Guest said. “The more widespread adoption of renewable energy created by such devices as the B3 will be a great benefit for individual homeowners and the planet.”

“The B3 Bypass is the solution the industry and anyone installing solar or renewable energy power sources have been looking for to continue to drive down costs and to take full advantage of their installation of such power sources,” said Q Factory 33 Chief Scientist Paul Cruz. “The ease of installation and immediate cost savings to those who deploy the B3 Bypass make it one of the most valuable cost saving weapons in the renewable tool box and produces a win for the installers, for the end users and for anyone involved in the renewable energy continuum.”

For example, if you’re one of the several hundred thousand Americans who have reserved a $35,000 Tesla for delivery, you may not be aware that the upgrade required to charge your new car at home could cost you an additional several thousand dollars, upwards of 10-20 percent of the cost of the car itself. In fact that applies to many EV’s. The B3 Bypass will cost a fraction of this for these Tesla owners and anyone purchasing an electric vehicle.

Without the expense of replacing the entire breaker panel, small businesses and homeowners can commission the installation of as many solar modules, wind turbines or renewable power sources as desired for a fraction of the cost. The B3 Bypass is estimated to cost $599.00, giving it the capacity to save residential solar installers between $2000 and $10,000 per installation.

iDemand says new charge controller eliminates AC loss from solar+storage systems

solar storage charge controller

iDemand Energy Storage (iDES3) has developed a single conversion charge controller that they say will shorten the time needed for electrical current to travel from solar panels to storage batteries, and in so doing, save energy. The idea is to take voltage coming in and convert it efficiently to low voltage, high amperage.

“You need high amps because batteries charge in amp hours,” iDemand’s Chief Operating Officer Raymond Trejo said. “Now everyone’s using standard PV inverters to convert solar energy to usable AC energy, and then they use a secondary hybrid inverter to take that AC and convert it back to DC.”

The problem with this method, according to Trejo, is a loss of efficiency, anywhere from 25 to 35 percent of the energy.

“Our approach was to develop a high voltage charge controller that takes the high voltage solar energy and converts it to low voltage, high amperage DC to charge the batteries,” he said. “So, it’s all DC energy dumped straight into the batteries. Other companies aren’t looking for a solution to the conversion problem because they design battery storage solely as a backup system. But our battery is capable of being fully grid-independent.”

PV Pointers: How to future-proof PV systems with a storage-ready inverter

Under development for nearly a year and a half, the new charge controller, which eliminates AC loss, is expected to go on the market in mid-June. It is best suited for large scale commercial and industrial operations that use a vast amount of electricity.

“Since this product doesn’t require a second inverter, it will save customers money,” Trejo added.
He pointed out that while the U.S. branch of Mercedes-Benz Energy recently announced a partnership with solar installer Vivint to sell backup storage, and SolarCity has merged with Tesla to do likewise, neither appear to be developing storage systems with a level of extended functionality equal to that of the new iDES3 charge controller.

iDemand’s battery lineup includes the 9-36 kilowatt hour Echo Indoor series suitable for most residential needs, the 9-72 kWh Echo Outdoor and 36-108 kWh Indoor/Outdoor Alpha. Commercial systems include the 36-108 kWh Indoor/Outdoor Alpha, and the Mega, the smallest of which comes in at 500 kWh, and can be customized in 108 kWh increments. They are all comprised of fifth-generation lithium iron phosphate, LiFePO4, prismatic cell technology, which is safe and will not self-ignite.
