Introduction
The Kia e-Niro and Hyundai Kona Electric share the same LG Chem NMC platform since 2018. Over 300 000 units sold in Europe. Their 39.2 kWh (Long Range: 64 kWh) battery packs are now entering the second-life market at €2 800-€5 500.
This guide covers how to reuse a Kia e-Niro or Hyundai Kona Electric battery for home solar storage in 2026.
Why Kia/Hyundai packs are great for home storage
- Modern chemistry — LG NMC pouch with proven longevity
- Good thermal management — active liquid cooling
- HV compatible (356V nominal)
- Well-documented — Bluelink app for diagnostic
- Widely available in EU — Kia/Hyundai sold heavily in France, Germany, UK, Norway
Downside: Slightly higher price than Renault Zoe/Nissan Leaf due to newer platform.
Total cost (64 kWh Kona / e-Niro in 2026)
| Component | DIY | Pre-built |
|---|---|---|
| Used 64 kWh pack (SoH 87%) | €4 800 | €5 200 |
| BMS-EV Controller | €500 | €500 |
| Sofar HYD 10 KTL-3PH | €2 100 | €2 300 |
| Enclosure + safety | €700 | €1 100 |
| Installation | €500 self | €1 500 |
| TOTAL | €8 600 | €10 600 |
Compare to new 64 kWh Pylontech Force H2 stack + inverter: €19 000-€23 000.
Savings: €10 000-€14 000 on a system that will run 10-14 years.
Kia e-Niro vs Hyundai Kona vs Nissan Leaf
| Factor | Kia e-Niro 64 kWh | Hyundai Kona 64 kWh | Nissan Leaf e+ 62 kWh |
|---|---|---|---|

Kia/Hyundai are functionally identical. Choose whichever is cheaper on your local market.
Common problems and BMS-EV solutions
“Kia BMS won’t wake up outside car”
→ BMS-EV emulates Bluelink wake-up signals.
“39 vs 64 kWh — same BMS?”
→ Yes — same protocol, same BMS-EV Controller works for both.
“Kia Niro Hybrid vs Kia e-Niro — same?”
→ No. Hybrid Niro has a small 1.6 kWh battery — different pack, different BMS.
“Genesis GV60 / Ioniq 5 / EV6 — supported?”
→ These use the newer e-GMP platform (800V) — different BMS. Supported by separate BMS-EV product for e-GMP.
FAQ
Q: Kia Niro Hybrid pack?
A: 1.6 kWh only — not useful for home storage. Look for e-Niro (39/64 kWh).
Q: Hyundai Ioniq (not 5) battery?
A: Old Ioniq Electric 28 kWh — supported. Newer Ioniq 5 uses e-GMP (800V) — separate product.
Q: Best inverter for 64 kWh Kia/Kona?
A: Sofar HYD 15 KTL-3PH at €2 400 — perfect voltage match.
Q: How long will it last as home storage?
A: Kia/Hyundai NMC pouch cells + BMS-EV careful cycling → 10-14 years.
