Here at REVOV we believe in freedom from the dependence. We distribute second life REVOV batteries in home, commercial and utility scale projects.

This is our typical ten kilowatt-hour setup from REVOV. What you will find is there is two battery modules and each battery module will be a 25.6 bolt which will be connected in series to give you your ten kilowatt-hour. Each battery module will be a 200 amp-hour battery and it will come with an external battery management system.

The battery management system will ensure that both batteries are safely looked after. Every battery has got eight individual cells. Lithium ion phosphate is the technology that we use here.

If anything goes wrong with any individual cell, the battery management system will pick it up and switch off the entire battery bank. The battery bank will ideally be connected to an inverter.

REVOV Battery Setup Explained

The inverters purpose is to create DC energy to AC current, or alternating currents so that all your appliances in house can perfectly work with this pure sine-wave technology. In this setup, you will find that the batteries will be connected from your bottom battery positive to your top battery negative. This will create this bottom battery to be a negative battery and the top battery will be a positive battery. With the BMS, you will find that there’s a negative in and a negative out will go to your inverter.

Your negative battery’s negative will be connected to the negative in on your battery management system and then from there, we’ll go up to inverter or your fuse or also your common bus bar. Your positive of your bottom battery will be in series with your top negative but your top battery which is now you’re positive battery will go directly through to your inverter.

On your battery management system, there is different harnesses. As you will see on top of your battery, there is a communication strap as what it got out of the electric vehicle and it will plug directly into one of four ports. Typically you will find ACB1, ACB2 to ACB3 and ACB4. ACB1 and ACB2 will go to your positive battery, or your top battery, while ACB3 and ACB4 will go to your bottom battery. You will find that if your cells are not balancing, you can easily take one and two with three and four and swap them around for balancing of the cells.

Right next to your negative going out, you will find a little B-plus (B+) on your battery management system. This is just to power your battery management system and this can connect either to the top of your positive battery or on the back of a bus bar. This will then bring power to the BMS and you will find it will make a beeping sound.

On the left-hand side of your BMS, there will be instruction indication of your voltage settings for your specific inverter and you will find on the right hand side your various dip switches. You

will only use these switches if you have 20, 30 or 40 kilowatt-hour systems. We have more than one bank in parallel. Each and every bank will look off to its own batteries with its own BMS and you will set your perimeters here to set up a master and a slave. One master can handle up to 80 slaves, so it just depends on what edges you allocate to it.

Right next to your dip switches you will find is an LED range of lights. This will show you your state of charge, your state of discharge and if any errors come up. If your inverter is not correctly set or there’s any problem with either your batteries or your battery management system, it will indicate certain alarms and certain areas right on here.

Right next to your last LED button, which is called run, you will see a little reset button. This button you will use either to power on, turn the power off or reset your entire system should there be an error. Next to that, you will coms in and coms out cable. Typically, this will be for communication to your inverter or to an inverter communication unit.
