About battery
A storage battery or accumulator is a device that generates energy following
a chemical process. Make sure you have chosen a suitable battery for this
inverter, to ensure a correct and optimal operation.
Battery preformance index
1. Capacity: Represents the amount of energy at maximum power composed
of the discharge current multiplied by the discharge time.
Capacity = Discharge current (I) x Discharge time (H)
2. Discharge rate: Represents the speed of each discharge current per specific
time
3. Discharge current: The discharge current is the output current.
It is usually expressed in Amperes or volume multiplied by a coecient.
4. Final discharge voltage: Represents the voltage when the battery is not
discharged. It is usually about 1.75V / cell
5. Nominal capacity: Represents the capacity after 20 hours of unloading.
6. Self-discharge rate: The battery is discharged even if it is not used. The unit
is C / unit.
Choosing the right battery
Because inverters need strong current when operating, the maximum
capacity and current of the battery are factors that determine the eciency
at which the inverter operates (50% - 100%).
These factors can also damage the battery.
Battery storage capacity depends on the maximum discharge current:
Maximum discharge current = Rated power / (storage voltagex0.85)
Battery storage capacity = average discharge current discharge time
Example:
PNI SP1000W has a rated power of 1000W, 12V input voltage:
Average discharge current = 1000 / (12x0.85) = 98A
If kept on for 2 hours:
Battery storage capacity = 98x2 = 196 Ah

9User manual
English
Choose a battery with a capacity greater than 196 Ah.

Despre baterie
Bateria de stocare sau acumulatorul este un dispozitiv ce genereaza energie
in urma unui proces chimic. Asigurati-va ca ati ales un acumulator potrivit
pentru acest invertor, pentru a asigura o functionare corecta si optima.
Index performanta baterie
1. Capacitate: Reprezinta cantitatea de energie la putere maxima compusa din
curentul de descarcare multiplicat cu timpul de descarcare.
Capacitate = Curent descarcare (I) x Timp descarcare (H)
2. Rata de descarcare: Reprezinta viteza fiecarui curent de descarcare
3. Curent de descarcare: Curentul de descarcare este curentul de iesire.
Este exprimat de obicei in Amperi sau volum multiplicat cu un coeficient.
4. Tesniune descarcare finala: Reprezinta tensiunea cand bateria nu se
descarca. In mod usual este aproximativ 1.75V / celula
5. Capacitate nominala: Reprezinta capacitatea dupa 20 ore de descarcare.
6. Rata de autodescarcare: Bateria se descarca chiar daca nu este utilizata.
Unitatea este C / unitate.
Dimensionarea corecta a bateriei
Deoarece invertoarele au nevoie de un curent puternic atunci cand
functioneaza, capacitatea si curentul maxim ale bateriei sunt niste factori care
determina eficienta la care functioneaza invertorul (50% - 100%).
Acesti factori pot determina si deteriorarea bateriei.
Capacitatea de stocare a bateriei depinde de curentul maxim de descarcare:
Curent maxim de descarcare = Putere nominala/(tensiune stocarex0.85)
Capacitate de stocare baterie = curent mediu de descarcarextimp de
descarcare
Exemplu:
PNI SP1000W are o putere nominala de 1000W, tensiune de intrare 12V,
deci:
Curent mediu de descarcare = 1000/(12x0.85)= 98A
Daca se mentine 2 ore pornit:
