Diesel generators are the most common means of electricity back-up during power outages in India but besides being noisy and polluting, they are also the most expensive means of alternative electricity. Such devices boast an operating efficiency of just 25%, require frequent maintenance and bring with them diesel storage requirements and fears connected to diesel theft.
Maharashtra-based Vision Mechatronics has installed a grid-interactive, lithium battery-based energy storage system coupled with a rooftop solar plant in South Delhi.

You’ve described some “features”, but I don’t think you’ve provided enough detailed information to evaluate the effectiveness of this system. Most of these residential battery storage systems are designed to flatten the duck curve of connected solar systems and provide short term backup power for a few hours, in the event of a power outage. Here in Northern California, when PG&E triggers a Public Safety Power Shutoff (PSPS) due to high velocity offshore winds during wildfire season, grid power can remain shut down for days, not just a few hours. That’s when you need a really, really big battery, one that can power your home for a few days, like the battery in the Tesla EV parked in your garage. Integrating EV battery storage with residential solar for emergency home power is way more important than these little residential battery systems. Most EVs used for commuting are probably at least 60% charged when they return home, after charging at work during the day. Thats way more stored power than a typical residential battery. When you start looking at storage in neighborhood micro-grid systems, EV storage looms large.
Hi Jerry, Rashi Gupta, of Vision Mechatronics has told pv magazine, in response to your query: “As mentioned in the article, OneBox is pre-configured as per [the] customers’ requirement and is customizable, so if there is a requirement to connect the electric vehicle to OneBox, for [more] storage, it can be done.”
Where can I buy one of this one box
You can use the live chat option at http://www.vmechatronics.com/OneBox we will assist you with your requirements of OneBox.
Thank you

I agree with Jerry’s comment, also what is the lifespan of these batteries and size?
Hi Abraham, The product pictured has a lifespan of 4,000 cycles at 80% depth of discharge.
Hi get one in tx
Hello Max Hall
Your reply to Abraham is too technical for some of us who are not so technical. Please explain “The product pictured has a lifespan of 4,000 cycles at 80% depth of discharge”. I am lost, what do you mean?
Hi Jacob, that’s probably the first time I’ve been accused of being too technical in relation to anything! In more simple terms, the developer says this product can be discharged until it is 80% empty 4,000 times.
Hi there
Our Solar teams here in South Africa have currently developed systems like these mobile Plug and play units from 1.5kw up to 15kw with battery storage starting at 1380watt up to 34.32Kw Lithium storage on 100% D.O.D for 6000cycles guaranteed on 10years. So these system are capable of providing sufficient energy backup to power an average house.
Good to see more and more development in this field. We also designed and manufactured a similar system, Ape’ SmartLINK @ Innovative Smart Solutions (www.smarthome.lk) and we also use same componets, Hybrid or Off-Grid Inverter, Li-ion battery, with our own Smart Control Unit (SCU) with Cloud hosted management platform. The challenges are to handle the EPS load with Air-conditioners and other heavy loads during power failure and also at the same time, to have the EPS load un-interrupted for critical equipment such as PCs and Routers etc., We have managed to connect EPS and On-grid loads selectively with patented PLC based Digital Load Separation devices, after many years of R&D. Would like to share relevant information with anyone who is interested.
