What hybrid inverters does BMS-EV work with?

BMS-EV has ready configurations for 60+ hybrid inverters: GoodWe (ES, EHB, EM), SMA (Sunny Boy, Tripower), Solax (X1, X3 Hybrid), Fronius (Symo Hybrid, Primo GEN24), FoxESS (H1, H3), Deye, Sungrow, Solis, Growatt, SoFar, Afore, Kostal and others.

Is BMS-EV safe for home use?

Yes. BMS-EV uses certified automotive-grade cells, monitors voltage of each cell, temperature control, short-circuit and overcharge protection. System operates in home conditions with 5-8x lower load than in a car, significantly extending battery lifespan.

What are the savings vs new energy storage?

30-70% savings compared to new commercial energy storage systems (e.g., Tesla Powerwall, BYD Battery-Box). With proper configuration battery + inverter + BMS-EV the cost per 1 kWh capacity is 200-400 EUR vs 600-900 EUR for new systems.

Can I install BMS-EV myself?

Yes — BMS-EV is designed for DIY-ers with basic electrical and electronic knowledge. The kit includes controller pre-configured for your battery + inverter, signal wiring, PL/EN PDF manual. We also offer remote configuration via TeamViewer and email/phone support.

What is the BMS-EV warranty?

24-month warranty on BMS-EV controller. Technical support (email, phone, TeamViewer) free during entire warranty period. In case of failure — replacement or repair within 14 days.

BMS-EV – Use Your EV Battery as Home Energy Storage and Reduce Your Electricity Bills

BMS-EV + EV battery vs Tesla Powerwall

✅ BMS-EV Controller + EV battery

~€4,590

(€590 controller + ~€4,000 used EV battery) = 50-80 kWh

❌ Tesla Powerwall 3

~€11,000

13.5 kWh (1 unit)

💰 58% cheaper + 4× more capacity

Why Are EV Batteries Better?

🔋 Automotive-Grade Certified Cells

EV batteries pass tests according to UN 38.3, UL 1973 and IEC 62933 standards – the most rigorous safety standards for lithium-ion cells. Typical home storage doesn’t have to meet such strict requirements.

💰 30-70% Savings Compared to New Storage

EV batteries retain 70-80% capacity after their service in the car. With 60-100 kWh capacity, they can power an average home for a whole week! The cost of such a solution is a fraction of the price of new energy storage.

🌱 Ecology and Second Life for Batteries

Instead of disposal – utilization. You extend the battery life by another 10-15 years, reduce your carbon footprint and support the circular economy. New EU regulations (2023/1542) require 70% recycling of lithium batteries by 2030.

⚡ 5-8x Less Stressed Than in a Car

At home, the battery operates in much gentler conditions – no sudden accelerations, extreme temperatures and continuous fast charging. This means longer life and stable operation.

How Does It Work?

☀️ PV → Inverter → Home – solar energy powers your home ⚡ Inverter → BMS-EV – surplus goes to storage 🔋 BMS-EV ⇆ EV Battery

– intelligent energy management

Compatibility

BMS-EV works with batteries from the most popular electric vehicles:

Nissan Leaf (24-62 kWh)
Tesla Model S/3/X/Y
BMW i3
Volkswagen ID.3/ID.4
Hyundai Ioniq/Kona
and many others…

Supported inverters: FoxESS, SMA, Solax, Sungrow, Sofar, Deye, GoodWe and others.

Safety First

⚠️ Working with high voltage is dangerous – that’s why BMS-EV has multi-layer protection systems:

Continuous voltage monitoring of each cell
Temperature control with automatic shutdown
Insulation resistance analysis and leakage protection
FAULT mode – immediate stop when anomaly detected
Compliance with UL 1974 and IEC 62933-5-3 standards

Net-Billing and Savings

With net-billing, energy fed to the grid is settled cheaply, while purchased energy is expensive. BMS-EV stores surplus in the EV battery and allows you to use it in the evening when solar energy is no longer available.

Self-consumption up to 90%+ instead of 30%
Return on investment in 3-5 years
Grid independence during outages
