How do I add extra solar to my Manager30 system and how much can I add?
This information is applicable to the following products:
- Manager30 Battery Management Systems (BMS12030S3, BMS12030S3-NA, BMS12030S3-UK, BMS12030S3-EU)
REDARC’s Manager30 is capable of utilising up to 520 watts of solar efficiently. However, there is no hard limit on the total amount of solar you can connect provided it meets the required system specifications.
For further assistance, we recommend seeing the support of an installer.
SOLAR INPUT REQUIREMENTS FOR THE MANAGER30
To function correct, all solar panels connected to the Manager30 must meet the following criteria:
- Unregulated output: Do not use panels with built-in regulators.
- Nominal 12V panels: Operating voltage must fall between 9 to 32 volts (VOC).
- Parallel configuration only: When connecting multiple panels, wire them in parallel, not in series. Parallel wiring ensures voltage stays within the acceptable range while increasing total output current.
INSTALLING MORE THAN 520 WATTS OF SOLAR
While 520W is the maximum amount of solar that the Manager30 can fully utilise at one time, adding more than 520 watts can improve overall system reliability by compensating for the following potential shortfalls.
- Reduced solar panel output due to non-optimal angles.
- Partial shading from trees, racks or rooftop accessories.
- Temperature-related efficiency loss.
Oversizing a solar array can help ensure consistent charging performance.
BEST PRACTICES FOR ADDING SOLAR PANELS
When installing solar panels, follow these recommendations:
- Match panel specs: Use the same panel type, brand and VOC rating for optimal compatibility.
- Avoid mixing panel technologies: combining different technologies can reduce system performance.
- Use quality cabling and connections: maintain voltage integrity and prevent power loss.
The Manager30 (BMS1230S3) can fully utilise 520 watts of Solar.
There is no limit to how much solar can be connected to your Manager30, providing the Solar input is unregulated, 12 volts nominal (9-32 volts) and, when multiple panels are used, connected in parallel.
A larger solar system (above 520 watts) will allow for any inefficiencies with panel mounting characteristics e.g. angle to the sun, partial shading, etc.
When adding another panel, either to the roof space or as a portable external panel, the panels should ideally be the same type, Volts Open Circuit (VOC) and brand for best performance.
