• Back up at 400W: ≥ 3 hrs
At 56.5kg versus the 150H's 58.9kg, this is a genuine difference in construction approach rather than a typo — internal design variations between warranty tiers don't always mean more weight equals more durability. Both deliver identical rated backup performance (3 hours at 400W), so the weight difference doesn't translate to a performance gap here.
For households using solar as a genuine daily power source (not just occasional backup), the longer warranty period is generally worth the modest premium over the 36-month version, since daily cycling puts more wear on a battery than occasional use, and the extended coverage period accounts for that more demanding usage pattern.
Confirm your solar PCU or inverter's voltage and charging current specifications are compatible with this battery's voltage and capacity, and have a licensed electrician verify the wiring, earthing, and ventilation meet safety requirements — proper installation matters as much as the battery specs themselves for long-term reliability.
TT construction generally supports better cycle life and deeper discharge recovery, which is part of why it pairs with the longer warranty tiers across Okaya's range — the trade-off is needing more vertical installation clearance compared to flatter, wider battery formats.
Daily cycling typically means slightly more frequent water checks than occasional-use batteries — checking every 1–2 months rather than the standard 1–3 month interval is a reasonable practice for batteries under consistent daily charge-discharge demand.
Manufacturing defects under normal use conditions for 60 months from purchase. Confirm specific registration requirements and maintenance conditions with Okaya Customer Care to ensure coverage remains valid throughout the period.
