• Back up at 300W: ≥ 1 hrs : 40 mins
At a 300W load — covering a few lights, a fan, and a small TV or charging devices together — this battery delivers approximately 1 hour 40 minutes of backup. For longer backup needs at that load level, you'd want to look at a higher-Ah model in the range.
It's a substantial jump — nearly double the capacity, which translates to either longer backup time at the same load or the ability to run more appliances simultaneously for a similar duration. If your essential load includes more than just basic lighting and a fan, this capacity tier is worth considering over the 40Ah range.
Same 75Ah capacity and backup performance, but the 075S carries a 60-month warranty (versus this model's 36 months) and weighs slightly more (38.5kg vs 37kg) to support that extended coverage — same battery family, different warranty tier.
At 37kg and 532×221×284mm, it's heavier than entry-level models, so a stable, level surface or a properly rated battery stand/trolley is recommended rather than placing it on an unstable shelf — standard practice for any tubular battery in this weight class.
It's built specifically for that pattern — designed to operate reliably in a partial state of charge and handle daily cyclic discharge, which is exactly what solar charging creates (charge during sunlight hours, discharge overnight), rather than the occasional full-discharge pattern of grid-backup-only batteries.
Manufacturing defects under normal use conditions for 36 months from purchase. Proper installation, correct distilled-water maintenance, and avoiding chronic deep discharge are typically required to keep coverage valid — confirm exact terms with your dealer.
