UNBOXING, UNPACKING AND SETTING-UP YOUR BATTERY

Delivery and Access

• The item arrives in a plywood container. You may need to disassemble the panels for easier access.
• To simplify moving the upright container to ground level, consider creating a temporary ramp from one of the panels.

Safety Precautions

• Due to its significant weight (140 Kg), it’s crucial to have at least six people assist with lifting, adhering to safety regulations.
• When manoeuvring the unit on wheels, exercise caution to prevent tipping. Ensure stability during movement and utilize the levelling pads, not the wheels themselves, to support the weight.

Wall Mounting

• For wall mounting, employ suitable fixings specifically designed for the wall material.
• Understand if it’s drywall, concrete, brick, or wood stud. This determines the appropriate types and sizes of anchors/fasteners.
• Ensure the wall itself can support the combined weight of the battery and mounting bracket.
• Doubling up studs or adding reinforcement might be necessary.
• You can remove the wheels for wall mounting. Remember to reinstall the bolts afterward to prevent dust and insect entry.
• 140kg is a very significant weight. Wall mounting might not be suitable for all wall types and locations. It’s crucial to assess the wall’s structural integrity.
• It’s highly recommended to consult with a structural engineer or a qualified contractor to determine the best mounting method and ensure safety.

Setting Up Your Battery

• This guide outlines the basic steps for installing your Fogstar battery and connecting it to your inverter.

Estimated Time

• The process should take roughly 20 minutes for one-battery system.

SETTING UP YOUR BATTERY

Please make sure that the battery is OFF and the BREAKER on the battery is in the OFF (DOWN) position before progressing.

Connecting the RS485 link cables

This diagram shows the RS485 Battery Link ports.

1. The left port (A) connects to the next battery (sending communication).
2. The right port (B) receives the connection from the previous battery (receiving communication).

The first battery (at the top of the pack) should only have one RS485 linking cable in the right port.
Your last battery should only have one RS485 in the left port. All middle batteries should have cables connected to both.

DIP Switches

• Now your batteries can communicate with each other, we need to tell them where they are in the order of things (at the moment they all think they are battery number 1).
• We can do this by adjusting the DIP switches. These are the red and white ‘ADD’ switches located on the front of the battery.

Connecting to your Inverter

• We provide 1.5m cables with M8 terminal rings, enabling you to connect your battery either directly to the inverter, or to an external busbar. We recommend connecting all negative leads first.
• Most inverters fit succinctly with the cables supplied. In some instances, you may need to connect the cables to a busbar first, and use the inverter cables supplied by your inverter manufacturer.

Updating the Inverter Protocol via the Touchscreen

You can update your Inverter protocol via the Touchscreen on the battery, this negates the need for downloading the Pbms Tools BMS Software.

1. Hit the ‘Settings’ button in the top right hand corner
2. Select CAN or RS485 communication type
3. Select the correct protocol
4. Click ‘Confirm’ and use the back arrow to navigate back to the main screen.

All of our units are configured to CAN > Pylon when shipped – in most instances, you won’t even need to change the protocol.

Connecting battery to PC and using the Pbms Tools software

For this, you will require a USB to RS232 cable – if you need one sent out, please get in touch with a member of our team. This requires a Windows PC (this process has been tested on Windows 7 and above).

1. On the initial connection to the USB port, Windows will automatically download drivers for the USB to RS232.
2. Download the PBMS BMS monitoring program from our Knowledge Hub.
3. You may be asked to install or update Microsoft .Net Framework, please proceed with this.
4. Open the PBMS Monitoring Tool.

Changing inverter protocol via BMS software

PbmsTools has plenty of powerful features, however we are just focusing on changing the inverter protocol for now.

1. Open the Realtime Monitoring Tab and select click ‘OPEN’ under the Serial Port section.
2. Select the System Config Tab. Under the Inverter Protocol section, click READ. This will read all inverter protocols currently on the BMS.
3. You can now change CAN and RS485 inverter protocols by selecting which one you require, and then pressing WRITE.
4. The password for writing your chosen inverter is Pz# 168178. The password needs to be inputted in the box next to the symbol. The box will turn green when the correct password is inputted.

You can now turn ON all your batteries with the POWER button, however your DC BREAKER should remain in the OFF (DOWN) position until you have changed your inverter protocol.

Pin Outs

• PACE has provided us with Pin Out information, allowing you to create your own communication cables if/when required.
• You may also find it useful to refer to the PACE BMS manual over at our website.

FREQUENTLY ASKED QUESTIONS

How many batteries can I connect together?

You can connect up to 15 units in parallel.

What protocols does your PACE BMS come loaded with?

The BMS has several pre-loaded inverter protocols with 'out of the box' support for Victron, Pylontech, Growatt, Sofar, Solis and Goodwe. It is crucial to note however, that inverter integration is not required for our server rack batteries to function.

How does the battery communicate with a Victron?

Victron communication via a Victron Cerbo GX which will need to be purchased separately. The batteries connect to a Cerbo GX BMS-CAN port from the CAN port on your main battery. The Cerbo GX then connects to your inverter via a VE.BUS cable. You'll require a type B Victron battery BMS to to BMS CAN cable for this.

What are the dimensions of the 15.5kWh Battery?

500 (w) x 230 (l) x 830 (h) These dimensions are without the wheels (which can be removed), the wheels add an additional 100mm to the height.

Can I connect my 15kWh battery to other makes/models of Batteries?

The Fogstar systems are not compatible with other types or models of battery on the market, this may be due to discrepancies in power/size of the unit, BMS or overall system compatibility. Please do not attempt to connect your Fogstar Rack Battery to any other make or model of Battery on the market.

Why are you not on the approved list for my chosen Inverter?

We may not be on the approved list for your chosen inverter because we believe that these lists are anti-competitive and limit consumer choice. Numerous battery approvals lists exist, particularly for popular inverters in the market. At Fogstar, we firmly believe that these lists serve only to restrict the market and reduce consumer options. Our mission is to make lithium batteries affordable and accessible to everyone, and we view approvals lists as a hindrance to progress and innovation across the industry.

Does self-installation void my warranty?

We understand that many people who purchase these batteries will be installing them themselves in preparation for system 'sign-off'. This does not affect the warranty at all.

How does the heating work?

Our batteries automatically activate their heating function when temperatures drop below 5°C, ensuring optimal performance even in frigid environments of -20°C.

Which way do i switch the breaker to turn it on/off?

Can my battery be mounted on the side?

Yes, you can mount the batteries on their side as part of your installation. However, this approach may make it a bit awkward when reading the battery vitals on the touchscreen, also, the weight of battery can cause some issues in this instance.

What are the charging parameters of the battery?

Bulk: 57.6 Float: 55.2 Low DC cut off: 43.2

How does the Active Balancer work?

The Fogstar Energy 15.5kWh unit contains a JK Active balancer, with a switch, enabling you to turn the function on and off. As all of our batteries contain matched and balanced cells, you shouldn’t have to use this function often, if at all. If you notice any significant disparity between the cells, we recommend putting the Active Balancing on, for two (2) to three (3) cycles. It’s worth noting that leaving your active balancer on indefinitely will result in a self-consumption of >1Ah per day on average.

Which Inverter Cables do I use?

Your Fogstar Energy unit will come with 1.5m inverter cables with M8 ring terminals.

What fixtures and fittings do I use to mount the unit to the wall?

Whilst we provide a robust mount for your unit if required, we have left the mounting fixtures firmly in your hands. It goes without saying that different wall types require different fixtures. Type of Wall Understand if it's drywall concrete brick, or wood stud. This determines the appropriate types and sizes of anchors screws fasteners. Strength of Wall Ensure the wall itself can support the combined weight of the battery and mounting bracket. Doubling up studs or adding reinforcement might be necessary. If you are unsure about the fixing requirement for your unit, please contact a structural engineer who will be able to advise on the best solution for mounting your battery.
