FAQs

Q: How many batteries can I connect together?
A: You can connect up to 15 units in parallel.

Q: What inverter brands does the PACE BMS work with?
A: The BMS supports various inverters like Victron, Pylontech, Growatt, etc., but inverter integration is not required for the batteries to function.

Why have we used PACE in our 48V Batteries?

When we were in the design stages of our rack system and looking at BMS solutions, our initial instinct (like many system designers on the market) was to ‘just go with’ JBD or JK. There’s something quite reassuring and rather copacetic about using a BMS so well recognised and established in the Global market. 

Although, when you start digging a little deeper into the specifications of these BMS, it was unlikely the most popular BMS could handle all of the requirements we were looking for.

PACE BMS

The core element for us was the multi-inverter protocol. The ease of integration was key to the functionality of our batteries, this is where many battery manufacturers on the market had gone wrong. Nobody wants to be spending hours re-programming the BMS to ‘play nice’ with their Inverter. PACE gave us the opportunity to implement a multi-inverter protocol that was unsupported by many BMS manufacturers.

Our mind was made up when we received a frustrated email from a customer saying they were having ‘major issues’ getting their BMS to integrate succinctly with their Victron Inverter. Yes - we know those challenges and we understand the frustrations. That customer was not the first, and they certainly wouldn't be the last.

Not only have we found a superb supplier of quality BMS overflowing with protective features, they also solve the issue of effortless inverter communication - allowing users to simply ‘plug and go’ for the top inverter brands on the market. For those of you not using one of these inverters (Victron, Sofar, Pylontech, Growatt, Solis, Goodwe), you still have the option to pull out the Pbms Tools software and input your BMS settings as required. 

Q: How do I connect the battery to a Victron inverter? (Optional)
A: You'll need a separate Victron Cerbo GX and a type B Victron battery BMS to VE CAN cable. The battery connects to the Cerbo GX, which then connects to your inverter using a VE.BUS cable.

Q: What are the dimensions of the 15.5kWh battery?
A: The battery is 500mm wide, 230mm long, and 830mm tall (excluding wheels). With wheels, the height increases by 100mm.

Dimensions of the battery ready for shipping are: 

L- 98.5cm, H- 40cm and W- 57cm. These dimensions are slightly bigger than above as these include the crate and packaging that the battery will be delivered in.   They are delivered in a crate that is attached to a pallet.

Q: Can I use your battery with other brands?
A: No, Fogstar batteries are not compatible with other brands due to potential differences in power, size, and system compatibility.

Q: Why isn't Fogstar on my inverter's "approved list"?
A: Fogstar believes these inverter lists limit consumer choice and restrict competition. They prioritise making batteries accessible and view these lists as hindering industry-wide progress. While they may not be officially "approved," the batteries are still be compatible in most instances.

Q: Does self-installation void the warranty?
A: No, self-installation does not affect your warranty.

Q: How does the automatic heating work?
A: When temperatures drop below 5°C, the battery automatically activates its internal heating system. This allows it to charge and perform optimally even in cold environments as low as -20°C, ensuring reliable operation in various climates.

Q: How does the battery arrive?
A: The 15.5kWh battery arrives in a plywood container that may require panel disassembly for easier access.

Safety Precautions

Q: How many people are needed to lift the battery?
A: Due to its weight (140kg), at least six people are required to lift the battery safely, adhering to all safety regulations.

Q: What safety measures should I take when moving the battery on wheels?
A: Use caution to prevent tipping. Ensure stability during movement and use the levelling pads, not the wheels, to support the weight.

Wall Mounting

Q: Can I wall mount the battery?
A: Yes, but it's crucial to consider the following:

  • Wall material: Use appropriate fixings designed for the specific wall material (drywall, concrete, brick, wood stud).
  • Wall strength: Ensure the wall can support the combined weight of the battery and mounting bracket. Doubling up studs or adding reinforcement might be necessary.
  • Professional consultation: It's highly recommended to consult a structural engineer or qualified contractor to determine the best and safest mounting method for your specific wall.

Q: What should I do with the wheels after wall mounting?
A: You can remove the wheels for wall mounting, but remember to reinstall the bolts afterward to prevent dust and insect entry.

Setting Up Your Battery

Q: How long does it take to set up the battery?
A: The basic installation process for a one-battery system should take approximately 20 minutes.
