Battery-storage systems and battery back -up systems.
They are not necessarily the same.
Battery storage systems are designed to work in conjunction with the existing power (micro) grid to provide additional power during peak demand times or when the grid is experiencing disruptions. These systems typically use renewable energy sources such as solar or wind power to supplement the grid’s energy supply, and they can be configured to automatically switch on and off based on grid demand and supply conditions.
On the other hand, battery backup systems are designed to provide uninterrupted power supply in the event of a power outage or grid failure. These systems use batteries to store energy when the grid is functioning normally, and then release that energy to power essential appliances and devices when the grid goes down. Battery backup systems can be configured to power an entire home or just a few critical devices, and they can be installed with solar panels or other renewable energy sources to maintain a sustainable power supply.
Grid-Assist and Off-Grid systems designed by Mangosat will provide both functions.
In summary, while battery storage systems are designed to provide additional power during peak demand or disruptions, battery backup systems are designed to provide uninterrupted power supply in the event of a power outage or grid failure.
Make sure to have your grid system ready for both.
Mangosat Battery Back-up Design, Selection and Implementation Service
Battery back-up is smart in regions that can suffer from severe weather, which are off-grid or with an unreliable power grid.
Mangosat can help you finding out when you need to add batteries to your system (and when it makes sense to skip them), we can help you selecting the right type of battery and we can help you sizing your battery bank so that you don’t under- or overcharge your batteries.
Eventually it is all about making sure your power back-up does do what it has to do and to preventing you from potentially shortening the batteries life-cycle.
Moreover, if you don’t have enough battery capacity, you will run out of power and end-up using a lot of (expensive) generator fuel. On the other hand, buying too much battery capacity can be a waste of money because there is no need for it. And to fully recharge your battery bank will cost you unnecessary extra power = recurring cash loss.
Every battery type has a different purpose and use case. And there are many many battery options. It is very common for people to make selection and design mistakes and this can affect system performance and the lifespan of the battery. Therefore, allow Mangosat to assist you in making the right choices. It will prevent you from disappointments and it will safe you serious money over time. Savings that can be calculated and quantified upfront.
A little bit of technical background
It is commonly known that batteries come in many shapes and sizes. In the solar industry, two battery chemistries work well for the purposes. Lead-acid and lithium.
You’ve got flooded lead-acid and sealed lead-acid batteries also known as VRLA (Valve Regulated Lead Acid). The latter group can be broken down into AGM (Absorbent Glass Mat) and gel batteries.
Some more important key terms and concepts:
Sizing battery banks
Understanding how to size a battery bank can sometimes be complicated.
The size of a battery bank very much depends on how much power (kWh) you will use or want to use on a daily basis. This is called your power profile. The result of the calculation is a battery bank capable of storing that much power after accounting for efficiency, DoD, ambient temperature and a few other things. A reliable battery bank with a long life span requires a good working battery charger with temperature compensation to prevent the system from chronic undercharging.
Mangosat Battery Bank Test, Monitoring & Maintenance Program
The Mangosat Battery Management System (BMS) monitors and protects the battery, keeping track of the state of charge, charging parameters, faults and data logging.
Batteries play an essential role, usually as a source of standby power. To ensure those batteries deliver their full performance when called upon to do so, you must rely on a regular testing regime. This is why a regular broad-based maintenance schedule is required to ensure standby batteries (when required) operate as expected.
There are, of course, other problems that can affect the performance of a battery bank. It has been stated, for example, that loose inter-cell connectors cause around 50% of the failures in battery banks. The connectors loosen because of the heating and cooling that takes place during charging and discharging.
Mangosat offers Its Customers an Affordable Battery Bank Test, Monitoring & Maintenance Program:
Upon physical installation of the battery (bank), one of our engineers installs our unique monitoring tool and thoroughly tests the individual batteries followed by the entire system. We keep extensive record of the results which are first compared to suppliers specifications.
The records are uploaded to our secured database and made available to the customer via customer’s individual web portal and via an app that can be downloaded and installed on a smartphone.
As of day one we start monitoring the health of the battery bank against its environmental conditions. The system generates an alarm when the internal resistance shows a 30% increase for a pre-defined period of time. NWNS will check with the customer if a follow-up maintenance visit is desired or required.
Note: IEEE 1188-2005 recommends quarterly maintenance of batteries. Until recently this was an expensive exercise because it had to be scheduled and an engineer had to visit the premises. Very often it was forgotten about or postponed until the next hard outage. Such an inconvenience.
Our unique monitoring tool can be installed anywhere and does NOT require Internet access hence it cannot be hacked. It is very low cost, reliable and perfectly designed for monitoring battery banks installed in harsh and/or remote locations.
A physical maintenance visit may very well provide useful information, but a series of tests carried out over a period of time will not only provide much more information, but will also make that information vastly easier to interpret.
A sudden change in a test result that has previously remained almost constant, for example, immediately suggests that further investigation is desirable, even if both the old and new values in isolation would be considered as falling within the acceptable range.
At first sight, monitoring the condition of batteries may appear to be a complicated undertaking. However, if the testing regime is properly planned and split into simple tasks that can readily be carried out with modern instruments such as our monitoring tool, the overall effort and inconvenience are small and the cost savings enormous.
How much can be saved depends on the individual situation. Please allow NWNS to understand your situation and calculate your potential savings. We are happy to do this in a transparent way without imposing any further obligations.
