Voltronic Axpert MAX vs MKS: Which Series Should You Choose?
Compare the Axpert MAX and MKS off-grid inverter series. Power output, PV input, parallel capability, battery compatibility, and value analysis.
Two Axpert Series, Different Strengths
The Voltronic Axpert lineup includes two main off-grid inverter series: the MKS (the proven, cost-effective workhorse) and the MAX (the newer, higher-performance flagship). Both are excellent products, but they target different needs and budgets.

When to Choose Axpert MKS
- Budget is the primary concern: MKS costs 30-40% less than MAX for similar capacity
- Small to medium systems: 1-5 kW single-unit installations
- 24V battery systems: MKS offers 24V options for smaller systems
- Simple, proven technology: The MKS has years of field-proven reliability
When to Choose Axpert MAX
- Larger systems: Single units up to 11 kW, or parallel up to 99 kW (9 units)
- Higher PV capacity: Dual MPPT and higher input power support larger solar arrays
- Mixed orientations: Dual independent MPPT tracks two different roof orientations efficiently
- Future expansion: 9-unit parallel gives more room to grow than MKS's 6-unit limit
- Maximum efficiency: 95-97% peak efficiency reduces energy waste
