Micro Energy Storage Setup – 2019 update

Micro Energy Storage Setup – 2019 update
Micro Energy Storage Setup NOTE: this is a grid-tied system setup with an energy back up to the batteries. This system is grid-tied only. The micro-inverter works only when the grid is present. If the grid is down, the system does not work. It is NOT an off-grid system. NOTE (2019 update): the illustrational picture shows a system we made in 2013 with some components which are no longer available (like the 36V regulator). We've nevertheless updated the list of components below so you can make the same system with components which are up to date and available in our e-shop. * * * * * A practical realization of a small size energy storage solution with 3.2 kWh of energy capacity with 230V/230W AC grid-tied power output. The basic concept of energy storage with easy expansion. The purpose of the installation is to store the energy in the batteries and release the energy slowly when needed.

Winston cells passed the China Army military safety tests

Winston cells passed the China Army military safety tests
The photo shows the punch-through simulating a shooting from 45 mm calibre anti-tank gun. Fully charged cells are punched through simulating the shoot-through from a military weapon. The purpose of the test is to see the safety and stability of the lithium cells. As visible from the photo, the cells remained complete, did not burn, did not set on fire and did not explode. This kind of extreme abuse proved that superiority of the Winston Battery lithium cells. These cells are suitable for all kinds of applications including the heavy duty and military grade installations.

Sailing Yacht with a 12V/200AH battery bank

Sailing Yacht  with a 12V/200AH battery bank
A reference project for a battery bank on a sailing yacht using the 4x WB-LFP200AH cells for the board battery and the BMS123 Smart. The battery pack is charged from the on-board AC/DC charger (35 Amp) and the generator (up to 80 Amp).

Initial charging FAQ

Initial charging FAQ
Check these FAQ published on our blog to understand the initial battery charging We remind all users of the LFP cells and LP batteries that the cells and batteries MUST be charged to full voltage level BEFORE assembling into a pack and before starting to be used. The new 3.2V LFP cells delivered from the warehouse are partially charged. However before the first use, it is essential to charge each cell to full capacity.

Maximal voltage during Initial charge of LiFePO4

Maximal voltage during Initial charge of LiFePO4
I want to make the initial charge of all the LiFePO4 cells to the same maximal voltage level of 4.0V. How can I do that? EDIT: This article gives the example of 4.00V charge level. The same information is to applied for charging to other voltage levels: e.g. 3.65V, 3.70V, 3.80V, 3.90V. Different voltage levels may be applied for initial charging based on the manufacturer specification. ANSWER: The best way it to find a power supply or a charger that will charge to the 4.0V directly. Another solution is to charge using the laboratory power supply or the regulated power supply that allows to set the final (maximal) voltage limit. We suggest to check with the local electronic components suppliers for these products.

LFP as starting battery

LFP as starting battery
LFP as a starting battery – two concerns Question: I want to use the LFP battery (4x 3.2V cells) for starting of my car. What SBM should I use to protect the battery? You cannot use a SBM to protect the starting battery. For starting the car, the current will be very high, hundreds or even nearly 1000 Amps, it is not possible to disconnect such high currents. WARNING: Additionally it is not possible to disconnect the battery from vehicle circuits. The car electronics may burn or become faulty of the battery is suddenly removed from the circuit, as a result of disconnection, during the operation (when the engine is running).

History of LiFePO4 Winston technology

History of LiFePO4 Winston technology
Difference between Winston Battery and other brands (1) What is the primary difference between the Winston Battery LiFePO4 products and other brands that also offer prismatic cells? 1. Technology history Thundersky Winston Battery The Thunder Sky Winston Battery company was the originator of the large capacity technology for the prismatic cells. The technology was created by Mr. Winston Chung. By means of partnerships with several companies TS-WB transferred the production facilities to partner factories. However the core know-how and technology processes were retained by Mr. Winston Chung.
