Victron SmartSolar 100/30 vs Renogy Rover Li 40A
Two common MPPT controllers for medium campervan systems, but not direct equivalents: Victron limits charging to 30 A and focuses on integration, size and monitoring; Renogy offers 40 A and more nominal solar power at 12 V.
Do not choose an MPPT by amps alone. Check cold Voc, Isc, array power, battery voltage, cable size and manufacturer limits.
30 A · 440 W at 12 V
Victron SmartSolar MPPT 100/30
A compact controller with built-in Bluetooth in the SmartSolar range and a VE.Direct port. At 12 V, Victron states 440 W nominal solar power and 35 A maximum Isc.
40 A · 520 W at 12 V
Renogy Rover Li 40A
Raises charging current to 40 A and nominal solar power to 520 W at 12 V. App connectivity depends on generation/compatible accessories; do not assume every version has built-in Bluetooth.
Technical comparison
30 A versus 40 A is only the start.
| Specification | Victron 100/30 | Renogy Rover Li 40A | Practical interpretation |
|---|---|---|---|
| Battery | Automatic 12/24 V | Automatic 12/24 V | Both support the two nominal system voltages. |
| Charge current | 30 A | 40 A | Renogy permits more battery current if the solar array can provide it. |
| Nominal solar power · 12 V | 440 W | 520 W | Both may suit a roof array around 400 W, but exact Voc/Isc still need checking. |
| Nominal solar power · 24 V | 880 W | 1,040 W | The difference scales at 24 V too. |
| Maximum Voc | 100 V | 100 V | Correct open-circuit voltage for cold conditions before approving series-connected panels. |
| Isc / solar current | Published maximum Isc: 35 A | Check current rating of the exact version | The voltage limit does not replace the current limit. |
| Max. efficiency | 98 % | Check the exact generation's curve/data sheet | Do not use an isolated efficiency figure to estimate daily generation. |
| Communication | Bluetooth + VE.Direct | RS485/RS232 depending on generation; app with compatible module | Victron offers a more direct monitoring path as standard. |
| Protection | IP43 electronics / IP22 connections | IP32 | Neither should be exposed indiscriminately to water or weather. |
| Weight | ≈1.3 kg | ≈2.0 kg | Victron takes less space and weighs less. |
| Dimensions | 130 × 186 × 70 mm | 238 × 172 × 77 mm | Physical height can matter in compact electrical cupboards. |
| Maximum terminal size | 16 mm² | ≈10 mm² / 8 AWG | Check actual cable size, ferrules and bending radii. |
