Description
The design is maintenance-free. The electrolyte is absorbed in a glass-fibre separator, and the VRLA valve design returns gases to the recombination cycle, so no water needs to be added. The grids are made of a high-tin alloy, and the specification also mentions the manufacturer's ESS technology. PSoC mode means the battery works for weeks without a full recharge, as happens in winter or in overcast periods at an off-grid solar plant. The tests to IEC 60896-21/22 apply to stationary valve-regulated batteries. Monoblocks are connected in series to the bus voltage of a hybrid inverter or charge controller, and blocks from the same batch are used for parallel strings.
How to choose
The sun | power VR M series is chosen when the battery is discharged and charged by the sun every day. For standby duty in a UPS or telecom cabinet, grid | power VR M is more logical, with a design life of up to 15 years for blocks above 50 Ah, or grid | Xtreme VR made of 99.99% pure lead with 12 V block capacities of about 78–209 Ah. If high discharge currents are needed for a few minutes, grid | power VR X at 57–166 Ah (C10) is suitable. The number of blocks is calculated from daily consumption and the permissible depth of discharge in the datasheet of the specific model.

FAQ
Is sun | power VR M suitable for use with a hybrid inverter in a private house?
Yes, the manufacturer positions the series for home solar storage systems with cycling and partial state of charge (PSoC). Compliance with IEC 61427 applies specifically to batteries for renewable energy sources.
Do the sun | power VR M AGM batteries need maintenance?
No water needs to be added, as these are sealed VRLA monoblocks. The terminal tightness and the voltage of each block in the string are checked periodically to spot imbalance in time.
How does sun | power VR M differ from grid | power VR M?
The sun series is designed for cycling and partial charge, while grid | power VR M is intended for standby duty in a UPS and has a design life of up to 15 years for blocks above 50 Ah.
To which standards are the sun | power VR M monoblocks tested?
To IEC 60896-21/22 for stationary VRLA batteries and IEC 61427 for batteries in renewable energy systems.
Where else are these monoblocks used, besides solar storage systems?
In off-grid street lighting, alarm systems and remote sites without a grid connection, where the battery goes through a charge and discharge cycle every day.
