As a product company, Joule Case generally does not provide installation services for customers. However, our team of experts is standing by to help you or your installation partner through every step of the process.
Joule Case will provide the necessary wiring to connect the batteries and inverter(s). The standard length is four feet of cables to connect the batteries to the inverter. Please contact us if a different length is required.
Yes! Our design allows additional batteries to be easily integrated into your existing system without any modifications. Simply add the battery to your existing system and connect using the supplied cables.
The batteries can be recharged VIA solar or utility power. Both options will be handled by the inverter(s). Joule Case also offers a standalone charger that can recharge off of a standard wall outlet.
The recharge time will depend on the available recharge power. The time can be roughly estimated using the following equation:
Total Battery Watts/(Service voltage x Service Amperage) = Charge Time in hours
Example - if your utility is a 30 amp, 240 service and you have four 5K Base batteries (20kwh):
20,000/(240 x 30) = ~2.78 hours. Please note that this is a rough estimate and will depend on a variety of actors.
The inverters will charge off a generator but that generator must be an inverter generator.
While it is possible to recharge your system off of a standard wall outlet through your inverter(s),it is not recommended. In order to avoid tripping standard outlet breakers, the charge rate must be set very low. If you want to charge using a standard wall outlet, a standalone charger is recommended. Please contact our sales team for information on available chargers.

Both the battery and inverter have settings that will prevent any equipment issues. When the system is fully charged the inverters will monitor the batteries and adjust as needed.
The status (percentage) of your charge is displayed on your 6K Pro/9K Max battery screen to the right of the letters SOC (State Of Charge) when you turn on the system.
For batteries without a screen, the charge can be viewed through your inverter.
The output voltage of your inverter system will dictate the required shore voltage. Example: if your system is set to output 240 volts, your utility will need to supply 240 volts.
The answer depends on the new source. You may need an adapter to connect to the new site. You may also need to change the charge rate in your inverter to match the new source. If the new source and plug are the same as your normal charging source, there should be no issues.
The combination of charging load and equipment load is too high for the connected utility/generator. This causes what is called power derating. The solution is to turn off equipment, lower the charge rate, and/or connect to a larger power source. Prolonged use in this state will likely cause the source breaker to trip.
While the batteries do not need active cooling, it is possible to overheat the batteries. Ensure that the batteries are not sealed in a location where heat is generated.
Yes. Please see your inverter manual for specifications. In practice we have not seen any temperature issues as long as the inverters are not sealed in an air-tight location.

When your batteries have reached the end of their useful life (less than 70% capacity), Joule Case will buy your batteries back! Our goal is to keep all of our products out of landfills and to send the raw materials back into the supply chain.
Joule Case has partnered with Redwood Materials for energy storage recycling and together our aim is to efficiently utilize resources to build a circular supply chain. Once your batteries have reached their end of usable life, we will pay you to send them back to us and we will work with Redwood to ensure that the component materials are re-introduced into the supply chain.
