Offgridtec AGM solar batteries are explicitly designed for use in solar and hybrid systems. AGM technology is clearly superior to conventional lead-acid batteries with liquid electrolyte and offers the following advantages:
Advantages of using Offgridtec AGM technology
- absolutely safe from leakage, no matter what position the battery is in
- screwable M8 terminals instead of battery terminals (100% fixed)
- 100% maintenance-free over the entire service life
- Life expectancy up to 10 years (depending on usage pattern)
- Highest quality level: Our batteries are all manufactured in A-quality from the best materials. This can best be seen in the weight of the batteries. Compare our products with those of other manufacturers!
- can be discharged deeper than lead-acid batteries
- mature technology, used in over 1000 Offgridtec solar systems
- very cycle-resistant, therefore predestined for use in solar systems
AGM batteries are somewhat more expensive to purchase than lead-acid batteries, but this pays off after just a few years, as lead-acid systems require much more maintenance and have a shorter life than AGM-based storage solutions.
Especially for smaller energy generation systems with a maximum storage capacity of 4-8kWh, AGM is the first choice.

Battery ordinance
You are legally obliged to return batteries. You can return them after use to our sales outlet or to a local municipal collection point.
Important information according to Battery regulation
Ordinance on the return and disposal of used batteries. Batteries and rechargeable batteries do not belong in household waste. Consumers are legally obliged to return used batteries. They can be returned to Offgridtec.com or to public collection points in the community.
Pursuant to § 10 of the Battery Act, a deposit of 7.50 Euro including VAT must be charged by the seller if the end consumer does not have a used starter battery on hand at the time of purchase. If the seller does not charge a deposit because the used battery has been disposed of properly or has been exchanged for new, this amount is not deductible from the purchase Price.
Welche ,,Spannung wenn Aufgeladen’“soll bei Victron smart shunt unter Batterieeinstellung eingetragen werden?
Können hohe Einschaltströme z.B. das Betreiben eines Kühlschranks über einen Wechselrichter der Batterie schaden?
Darum ist es wichtig, die Batteriekapazität und auch den Typ, dem Verbrauch bzw. Vorhaben anzupassen und großzügig zu dimensionieren, mit genügend Sicherheitsreserven. Nur so kann eine lange Nutzungsdauer erzielt werden.
Bis zu wie viel % kann die Batterie regelmäßig ohne großen Verlust der Lebenserwartung entladen werden?
Beispiel: Eine 100Ah AGM Batterie hat eine nutzbare Kapazität von 50Ah.
Je kleiner davon der genutzte Anteil einer Batterie ausfällt, umso länger die Lebenserwartung.
Optimal ist es, die Batterie max. um 30% zu entleeren, entspricht am Beispiel 20-30Ah optimal nutzbare Kapazität.
