OPzS vs OPzV — which one for your project?

OPzS (flooded tubular): lowest cost per amp-hour over a project life; requires periodic water topping — best where maintenance teams are available (mini-grids, large solar stations).
OPzV (gel tubular): fully maintenance-free sealed construction — best for remote telecom sites, unmanned stations and dusty environments.
Both types ship as individual 2V cells; systems are assembled to 24V / 48V / 110V / 220V with busbars and connectors we can supply.

*Sample specs — final parameters confirmed per project before order.
