6 checks for home-battery providers:

  1. Manufacturer + cell supplier transparentestablished names (Tesla, BYD, LG, Sonnen, Victron) have track record; obscure private-label = risk
  2. Fire certificationCE + IEC 62619; LFP chemistry (LiFePO4) safer than NMC for homes
  3. 10-year / 6,000-cycle warranty minimum; read fine print"performance" vs "product"
  4. Installercertified, KvK-registered, insured at 6-figure level
  5. Insurancecheck with your property insurer that the battery is covered (some require disclosure + premium surcharge)
  6. Safety placementnot living room or escape route; technical room or garage. Red flags: <€2,500 for 10 kWh, "warranty" via opaque intermediary, uncertified installer. When in doubt: ask for reference projects.
