# Energy Storage

We specialise in Victron Energy storage systems — from 5 kWh residential installations to large-scale industrial solutions. As an authorised Victron installer, we guarantee the highest quality.

## Scope of service

### Victron Home Storage

MultiPlus-II and Quattro systems with LiFePO4 batteries (Pylontech, BYD). Capacity from 5 to 50 kWh, expandable at any time.

### Commercial Storage

Systems up to 200 kW based on Victron Energy for critical business infrastructure. Guaranteed power supply and peak shaving.

### Large-Scale Systems

Sinexcel and PITES solutions for industrial applications. Scalability up to megawatts of power for large enterprises.

### PV Integration

Full integration with existing or new solar PV installations. Maximise self-consumption and optimise net-billing performance.

## Frequently asked questions

### How much does a Victron energy storage system cost?

A 5 kWh Victron storage system starts from PLN 15,000, a 10 kWh system from PLN 25,000. The price depends on capacity, inverter power rating, and system configuration.

### Can I add storage to my existing solar system?

Yes, Victron Energy systems can be integrated with an existing PV installation. We will conduct an audit and recommend the optimal solution.

### How long will a battery storage system last?

LiFePO4 batteries have a lifespan of over 6,000 cycles, which translates to 15–20 years of use. The manufacturer's warranty is typically 5–10 years.

### Which batteries do you recommend?

LiFePO4 (lithium iron phosphate) — Pylontech, BYD, or Victron. Safe, 6,000+ cycle lifespan (15–20 years), no fire risk.

### Will energy storage pay for itself?

At current energy prices and under the net-billing scheme — yes, in 7–10 years. Factoring in rising electricity costs and the value of backup power — sooner.

### Victron or Huawei — which to choose?

Victron = premium, fully modular, off-grid capable, best for backup power. Huawei = simpler, more affordable, excellent for self-consumption in on-grid systems.

### Can I go fully off-grid?

Yes, with solar PV and an appropriately sized Victron storage system. We design off-grid systems with a backup generator as a safety net.
