How to Adjust Your RENOGY Inverter Charge Rate at Caravan Parks
If you’ve ever arrived at a caravan park, plugged into power, and suddenly tripped the site’s circuit breaker, your inverter charge rate may be set too high for the available power supply.
This is a common occurrence at caravan parks with limited amperage outlets and is not a fault with your RENOGY inverter charger. Many caravan parks operate older electrical infrastructure or provide lower current limits on individual sites, which can cause high-charge-rate inverter chargers to exceed the available power and trip the breaker. The same issue can also occur when charging from portable generators.
Fortunately, adjusting the charge rate through your RENOGY One Core display is quick and easy.
Why Change the Inverter Charge Rate?
When connected to mains power, your inverter charger will draw power to recharge your batteries. If the charge rate is set too high, the total power draw from the inverter charger can exceed the available power supply.
Common situations where reducing the charge rate may be beneficial include:
- Caravan parks with limited power availability.
- Older caravan park electrical infrastructure.
- Shared power circuits.
- Portable generators.
- Off-grid power supplies.
- Temporary power connections.
Generator Charging Considerations
If you’re using an AusTuff 3.3kVA Generator, Austrack recommends reducing the inverter charge rate to approximately 30A to 40A to prevent overloading the generator during battery charging.
Other generator brands and models may have different output capacities, so always refer to the generator manufacturer’s specifications when determining the appropriate charge rate.
Symptoms of a Charge Rate That Is Too High
You may need to reduce your inverter charge rate if you experience:
- Caravan park circuit breakers tripping.
- Generator overload warnings.
- Generator stalling or struggling under load.
- Loss of incoming AC power.
- Charging interruptions when connected to mains power.
In most cases, these symptoms indicate the available power source cannot supply the demand being requested by the inverter charger.
How to Change the Charge Rate on the RENOGY One Core
Step 1 – Turn On the Inverter
Using the Vision Screen, ensure the inverter is switched on before making any changes.
Step 2 – Open the Inverter Settings
On the Renogy One Core display, select RIV1230RCH from the device list.
Step 3 – Access the Settings Menu
Press the three dots in the top-right corner of the screen to open additional settings.
Step 4 – Adjust Charge Amps
Select Charge Amps and enter your desired charging current.
Recommended Settings
| Power Source | Recommended Charge Rate |
|---|---|
| Standard mains power | 70A |
| AusTuff 3.3kVA Generator | 30A to 40A |
| Smaller generators | Refer to manufacturer specifications |
| Limited caravan park supply | Reduce as required |
Step 5 – Confirm the Change
Once adjusted, the inverter charger will automatically operate at the newly selected charge rate.
What Charge Rate Should I Use?
For most situations connected to a reliable mains power source, a charge rate of 70A is suitable.
However, if you’re connected to:
- A smaller generator
- A heavily loaded caravan park circuit
- An older caravan park power outlet
- A restricted off-grid power source
Reducing the charge rate can help avoid nuisance tripping and ensure a more reliable charging experience.
Final Thoughts
If your caravan park breaker keeps tripping or your generator struggles while charging your batteries, it may simply be a case of reducing your inverter’s charge rate.
This is a normal adjustment and does not indicate a fault with your RENOGY inverter charger. Different power sources provide different levels of available power, and matching your charge rate to the power supply can often resolve charging issues quickly and easily.
By understanding how to adjust your inverter charger settings, you’ll enjoy more reliable charging whether you’re staying at a caravan park, travelling off-grid, or powering your setup from a generator.
