Power
Usual use power to describe about how efficiency the total of energy is transferred or transformed in a given time, Energy equal average power * time
Power Density
Power available per unit of volume
Power Factor
Voltage and current could out of phase from each other.when that are in phase apparent power(VA) is equal to power and the power factor is 1.0 and reactive power(VAR) is zero. Solar inverter can often be programmed to have the ability to work at different power factors. Truly understanding this concept is an advanced topic and involves trigonometry
Power Quality
The compatibility of power produced with the load it is connected to as assessed through voltage, frequency, and waveform(like pure sine wave solar inverter)
Primary Batteries
An solar storage battery that in not recharged and is optimize used when recharging is impractical and not needed.
Ramp Rate
When adjust for up and down in output per minute is called the ramp rate and is often expressed as megawatts per minute, this is how fast a power plant can ramp up in units of power per time. When someone says kilowatts per hour, they usually mean KWH and should read this book. kW per hour would be an example of a ramp rate which is how fast a power plant can power up
Reserves
A reserve capacity that can be called on when part of the normal electric supply resources become unavailable
Resistance
A scale of how difficult to current flow in an electrical circuit, measured in ohms
Round Trip Efficieny
Rate of useful energy output to useful energy input, in other words, the level of energy losses when moving between storage and deployments. Energy Storage System output per energy input
Self-consumption
The process where grid-connected residential energy storage takes in the excess generated energy from the grid when more energy is being produced than consumed, and then uses energy stored in the solar battery when energy consumption is higher than the amount produced
Separator
A physical structure that isolates the cathode and the anode and selectively lets some things through
Series
Describes a way that components in an electric circuitry are connected. In a series circuit, the current that flows through each of the components is similar, and the voltage across the circuit is the sum of the individual voltages
Sodium Sulfur Battery
A type of molten-salt battery constructed from liquid sodium and sulfur that operated at very high temperatures. the active materials are molten sulfur as positive electrode and the negative is molten sodium. A solid sodium alumina separates both and serves as the electrolyte
Solid state batteries
A battery technology that uses solid electrodes and a solid electrolyte, instead of the liquid or polymer gel electrolytes found in lithium-ion or lithium polymer batteries.
Specific Energy
A measure of nominal battery energy per unit mass, for instance, your battery may have a specific energy of 100WH/KG
We are a Chinese manufacturer of solar energy storage systems, our products consist of lifepo4 batteries(Lithium-ion), solar inverters, solar controllers as well as solar panels, etc…..We have 600 Employees and 40 science engineers and 40,000 square meters for Producing products (Divide into two factories, one in Guangdong in the south of China and another in Hunan in the middle of China), we used to be a prominent supplier for some mobile company such as “HUAWEI”, “OPPO”, “VIVO” Etc… last year we made roughly 50 million dollars in total, provide assurance solution for solar power storage, please contact me if you wanna discuss it further, your friend Robert Burns: +86013702992950(MB&WHATSAPP)
