How long does an OPzS battery last in an off-grid installation?

20-25 years, provided distilled water is topped up every 1-3 years; it remains the most cost-effective long-term option for a family home.

What's the difference between OPzS and OPzV?

OPzS is flooded tubular (needs water top-ups); OPzV is its sealed gel version, maintenance-free, designed for unventilated technical rooms or telecom cabinets.

Is LiFePO4 lithium worth it over lead-acid for renewables?

A 48 V LiFePO4 rack takes up half the space, tolerates 100% depth of discharge without penalty, lasts 10-15 years and integrates natively with Victron, SMA or Fronius inverters.

How do I know how many kWh I need for my renewable bank?

Multiply your daily kWh consumption by the days of autonomy without generation you want to cover, adjusted for the maximum depth of discharge of your chosen technology (50% lead, 80% lithium).

Do these batteries also work for wind or mini-hydro, not just solar?

Yes. Small wind and mini-hydro systems use the same 200-800 Ah AGM or OPzV banks at 24/48 V as an equivalent off-grid solar installation.
