ECOHOLICS - Acronyms

#

#S#P: Number of Solar Panels in Series and Parallel - 3S2P means three panels in per series string, two strings in parallel. more...

A

A: Amp or Ampere - Unit of electrical energy associated with current for alternating current (AC) and direct current (DC) circuits. The formula commonly used is: Watts = Volts × Amps
AC: Alternating Current - A method of power delivery where electrical current periodically reverses direction, usually with sine wave waveform. In North America this includes 240 volt split phase which ultimately is two 120 volt circuits which are 180 degrees out of phase with each other. In most of the rest of the world alternating current is 240 volt with a hot, neutral, and ground.

B

BMS: Battery Management System - Circuitry which manages the internal battery cells of a EF solar generator in order to balance and regulate the charging for best performance and while avoiding overheating

D

D2: DELTA 2 - Small, lightweight, yet powerful enough for most 120V loads
D2M: DELTA 2 Max - Upgraded from the DELTA Max with two solar inputs, lithium iron phosphate (LFP) batteries, and whisper quiet fans
DC: Direct Current - EcoFlow solar generators can supply 12 volt direct current using the car power port, a DC5521 bullet style port, or an Anderson Port (DELTA Pro only)
DM DM2K DM2000 DM1600: DELTA Max - Older lithium nickel manganese cobalt (NMC) power station in 2000kwh and 1600kwh sizes
DP: DELTA Pro - It is big. It is heavy. It can handle almost any load. The DELTA Pro has a 30A 120V RV outlet, a 30A 12V Anderson port, and an Infinity port which allows you to connect two DELTA Pros into a Double Voltage Hub or a Smart Home Panel
DPU: DELTA Pro Ultra - A new product offering along with the Smart Home Panel 2 (SHP2) were inintially leaked at a conference in Germany, Aug 2023 for the whole-home market. Technical details are sparse until the official product release sometime later. The initial information shows a separate head unit which includes the inverter and external outlets with 240 volts, 7200 watts, 30 amps using up to five stackable 6 kilowatt batteries.
DVH: Double Voltage Hub (North America only) - This allows you to connect two DELTA Pros or two PowerKits Hubs together to produce 240v split phase

E

EB: Extra Battery a.k.a Smart Extra Battery - Many newer DELTAs and some older RIVERs can accept extra batteries. Early on, the extra batteries had to match the DELTA model (DELTA Pro to DELTA Pro Extra Battery, DELTA Max to DELTA Max Extra Battery) precisely, but lately with the DELTA 2, DELTA Max, and DELTA 2 Max some mixing and matching is possible.
EPS: Emergency Power Supply - Used to describe the use of an EcoFlow solar generator to power devices or a household during a power outage, differentiated from a fast switching uninterruptible power supply (UPS) because the EcoFlow products require about 30ms to switch to battery power.
EF: EcoFlow

H

Hz: Hertz - Electrical unit that describes the frequency of an alternating current circuit. North American houshold outlets are 60 hertz while much of the world uses 50 hertz.

I

Imp: Current at Maximum Power - Maximium current with no load connected to a solar panel.
Isc: Short Circuit Current - Maximum current on a solar panel with the terminals shorted

K

kW: Kilowatt - Unit of energy equal to 1000 watts. With respect to EcoFlow solar generators, the display will show watts or kilowatts of input and output on the display.

L

LFP: Lithium Iron Phosphate (LiFePo₄) - Lithium Iron Phosphate chemistry batteries are typically rated for 3000 full cycles to 80% capacity which is close to 10 years as opposed to Nickel Manganese Cobalt which are usually rated for 800 full cycles to 80% capacity. Lithium Iron Phosphate systems are much safer and less prone to experience thermal runaway

M

MC4: Multi-Connect 4mm - This is the standard solar cable connector for most solar panels and solar extension cables.
MPPT: Maximum Power Point Tracking - This is a technique used by EcoFlow's built-in solar controllers to maximize the solar input
MTS: Manual Transfer Switch - This enables the ability to safely plug a DELTA or a pair of DELTA Pros connected to a DVH to your house electrical panel and manually choose which circuits to power from the grid or from the DELTA battery. EF sells several varieties of manual transfer switched depending on whether you need 120V or 240V

N

NMC: Nickel Manganese Cobalt - Originally called Lithium-ion but now named Lithium-ion Nickel Manganese Cobalt to differentiate it from other chemistries like Lithium Iron Phosphate. Ecoflow Nickel Manganese Cobalt batteries are rated for 800 full cycles to 80% capacity.

P

PK: Power Kits - EcoFlow's compact modular power solutions for RVs and tiny homes. These are components comprised of a PowerKits Hub, a Smart Distribution Panel, Batteries and an optional Remote Display. PowerKits come a variety of bundles and sizes: 2kWh, 4kWh, 5kWh, 10kWh, 15kWh,

R

R2: RIVER 2 - A small LFP portable power station is very lightweight and useful for recharging phones, tablets, and laptops
R2M: RIVER 2 Max - A midsize LFP portable power station
R2P: RIVER 2 Pro - A large LFP portable power station
RP: RIVER Pro - A large NMC portable power station with an extra battery port to support the RIVER Pro Extra Battery

S

SG SGDF: Smart Generator - EcoFlow's original Smart Generator was gasoline-only, but their newest version is dual-fuel: gas and propane. Unique to the EcoFlow Smart Generator is its autostart feature which keeps DELTA solar generators charged when the batteries are empty. It also has an XT-150 connector to charge DC-to-DC (requires an adapter for DELTA Pro or Power Kits. The Smart Generator can also charge solar generators that don't have an XT-150 port via its 20 amp outlet.
SHP: Smart Home Panel - An SHP allows you to attach up to two DELTA Pros or Power Kits with EBs to power your home, control a mix of 120 volt single phase (up to 10) or 240V split phase circuits to use grid or battery power. It also has powerful automations to allow seamless operation to deal with power outages, low battery conditions due to clouds, etc.
SHP2: Smart Home Panel 2 - Introduced at a German conference to support the new DELTA Pro Ultra
SMPS: Switched Mode Power Supply - Although EF doesn't sell an SMPS, they are often used with a DELTA Pro to avoid pass-thru mode which limits its 30a output to 15a when the DP is plugged into a household outlet. This allow for AC charging via the solar inputs.
SoC: State of Charge - Level of charge in a battery relative to it's capacity

U

UPS: Uninteruptable Power Supply - Users often add an uninteruptable power supply between an EcoFlow solar generator and their equipment as EcoFlow products require more than 30ms to switch in the event of a power outage. Some equipment like computers and routers need faster switching times to avoid rebooting.

V

V: Volt - Unit of electrical potential used to describe types of electrical systems. For example a typical car battery is 12 volts DC, a North American household outlet is usually 120 volts AC, the rest of the world uses 240 volt AC. With respect to EcoFlow products it is important to stay below the voltage limit of the maximum solar input specifications to avoid damage to the solar controller. The formula commonly used is: Watts = Volts × Amps
Vmp: Voltage at Maximum Power - Maximium voltage that a solar panel can produce while under load under standard testing conditions
Voc: Voltage at Open Circuit - Maximum voltage with no load connected to a solar panel

W

W: Watt - Unit of electricalicity equivalent to Volt-Amp (VA). The formula commonly used is: Watts = Volts × Amps
W1 W2: WAVE, WAVE 2 - The EcoFlow Wave is an efficient air conditioner which can run from 120V AC, 12V DC (fan only) or DC to DC via an XT-150 cable using a compatible extra battery or solar generator. The WAVE 2 addes heat pump capability so it can act as an air conditioner or a heater.
